Yb:YAG-manufacture,factory,supplier from China

Yb:YAG (Ytterbium-doped Yttrium Aluminum Garnet) is one of the most promising laser-active materials with a large absorption bandwidth and typical emission at 1030 nm. Yb:YAG is more suitable for high power diode-pumped lasers than the traditional Nd-doped systems. The broad absorption band enables Yb:YAG to maintain uninterrupted pump efficiency across the typical thermal shift of diode output.

Yb:YAG's advantage is a wide pump band and an excellent emission cross section. It is ideal for diode pumping. The broad absorption band enables Yb:YAG to maintain uninterrupted pump efficiency across the typical thermal shift of diode output. High efficiency means a relatively small dimension Yb:YAG laser crystal will produce high power output. Based on the YAG host crystal, Yb:YAG can be quickly integrated into the laser design process.

Ytterbium Doped Yttrium Aluminum Garnet (Yb:YAG) is more suitable for diode-pumping than the traditional Nd-doped laser crystal. Compared with the commonly used Nd:YAG, Yb:YAG has the following advantages: three to four times lower thermal loading per unit pump power and much larger absorption bandwidth to reduce thermal management requirements for diode lasers, longer upper-laser level lifetime.

Solid Laser DyesThere is some work on dye lasers based on solid media, e.g.

WISOPTIC offers both plate and cube PBS for a variety of wavelength ranges and power handling requirements.

Polarizing Beamsplitters (PBS) are designed to split light by polarization state rather than by wavelength or intensity. PBS are often used in semiconductor or photonics instrumentation to transmit p-polarized light while reflecting s-polarized light. Optical isolators use PBS to eliminate feedback-induced damage. PBS are typically designed for 0° or 45° angle of incidence with a 90° separation of the beams, depending on the configuration.WISOPTIC offers a wide variety of PBS in a range of configurations including plate, cube, or lateral displacement.

BBO is an effective NLO crystal for the SHG, THG, or FHG of Nd:YAG lasers, and the first-rate NLO crystal for the FHG at 213nm. Conversion efficiencies of more than 70% for SHG, 60% for THG and 50% for 4HG, and 200mw output at 213 nm (5HG) have been obtained through using Wisoptic's BBO, respectively.BBO is also an efficient crystal for the intracavity SHG of excessive energy Nd:YAG lasers. for the intracavity SHG of an acousto-optic Q-switched Nd:YAG laser, greater than 15 w average power at 532 nm generated via an AR-coated BBO crystal produced by Wisoptic.

Polarization optics is important for both intra and extra cavity use. By using high contrast thin film polarizers in their design, laser engineers can save weight and volume within the laser system without influencing the output. Compared with polarizing prisms, polarizers have larger incident angle and can be made with larger apertures. Compared with polarizers made from birefringent crystals, the advantage of thin film polarizers made from UVFS or N-BK7 is that they can be fabricated in very large sizes, therefore are particularly well suited for high laser powers and UV wavelengths.

LBO (LiB3O5) is an excellent non-linear crystal of Borate-family following BBO. LBO has advantages of good ultraviolet transmittance (210-2300 nm), high laser damage threshold and large effective frequency doubling coefficient (about 3 times of KDP crystal). Therefore LBO is commonly used to produce high power second and third harmonic laser light, especially for ultraviolet lasers.LBO has large band gap and transparency region, high non-linear coupling, good chemical and mechanical properties.

Nd:YVO4 is the most efficient laser crystal for diode-pumped solid-state lasers. The good physical, optical and mechanical properties make Nd:YVO4 an excellent material for high power, stable and cost-effective diode-pumped solid-state lasers.

YLF is birefringent, which eliminates thermally induced depolarization loss. The gain and the emission wavelength of Nd:YLF are polarization dependent: there is the stronger 1047nm ray for π polarization, and a weaker one at 1053nm for σ polarization. Nd:YLF provides alternative to the more common Nd:YAG laser crystal for near IR operation.

The Ceramic Laser Reflectors are high reflectance cavities used in solid state and CO2 laser systems. They are built either as a one-piece or two-piece system based on customer requirement.Ceramic cavities produce diffuse reflectance, which offers a very uniform beam profile. This diffuse reflectance also distributes light and consequently decreases hot spots in the pumped medium. These completely dense materials (e.g. Al2O3) exhibit higher strength and scratch resistance than traditional polymeric and thermoplastic materials.

Ceramic Laser Reflector (Ceramic Laser Cavity) works particularly well in Ruby, Nd:YAG, or Alexendrite laser pumping chambers and can be a highly cost effective alternative to metal coated reflectors. Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity.

Wisoptic' standard and precision quality laser windows are fabricated from a variety of substrate materials, e.g.  UVFS and N-BK7. They are available either with or without AR coatings, and with dia from 12.5 to 101.6 mm and thickness from 1 to 15 mm. Also we offer uncoated rectangular windows with aperture from 15 x 20 to 50.8 x 50.8 mm and thickness from 2 to 10 mm.

Dye laser headpiece made from WISOPTIC has very high conversion efficiency: 65%~75% for 532/585nm, 45%~55% for 532/650nm.

A right angle prism is an optical prism designed to deviate light by 90° or 180°, depending on the orientation of the prism and the face through which light enters. The joining edges and faces are perpendicular to the base faces, and all joining faces are rectangular. They are often  preferable to plane mirrors, because they are easier to mount and align.

Polarizer is a kind of optical filter where the light transmission depends strongly on the polarization state. Normally, light with linear polarization in a certain direction is passed, and light polarized in an orthogonal direction is either absorbed or propagated to a different direction.For other directions of linear polarization with an angle θ against the“passing”direction, the transmission exhibits a cos2 θ dependence. That can be understood by considering that linear polarization state as a linear superposition of the "passing”and the“blocked”state.Most polarizers act

Thin Film Polarizers are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Polarizer is used to change un-polarized beam into linear polarized beam.

A corner cube (or cube corner), also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam's angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.Wisoptic offer a wide variety of retroreflectors at competitive prices and lead times, and are able to accommodate the most demanding requirements.

Right angle prisms are generally used to bend image paths or redirect light at 90°. This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted.

Corner cube prisms are optics which act as corner reflectors. The basic operation principle is that there are internal reflections on three mutually orthogonal prism surfaces, producing a direction of a reflected beam which is nominally parallel to the direction of the incident beam – with the accuracy limited only by the accuracy of the surface orientation of the prism. Precision prisms can offer excellent parallelism of incoming and reflecting beams. It is usually specified as an angular deviation, e.g.
