Dye Handpieces 585nm-manufacture,factory,supplier from China

WISOPTIC use in-house made dye laser cells to make dye laser handpieces. Pure input beam at 532nm is required to produce output beams of 585nm/595nm (energy over 100 mJ) and 650nm/660nm (energy over 80 mJ).

Dye Laser Handpiece are devices that screw onto the end of the laser's arm and convert the energy that the laser produces into different, new wavelengths of light.The two most common dye handpiece wavelengths are 585 nm and 650 nm, which attach to Q-switched Nd:YAG lasers. For these wavelengths to be produced, the Nd:YAG's 1064 nm wavelength is frequency-doubled to produce the 532 nm wavelength, which is then converted by the dye handpieces to produce either 585 nm or 650 nm. WISOPTIC use in-house made dye laser cells to make dye laser handpieces.

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

Polymer-matrix Gain Medium for Pulsed Dye Laser (PDL)Polymer matrix can be used to make solid laser gain medium of dye lasers.  Compared with the commonly used liquid-state dye laser unit, the solid-state material has many advantages, such as the convenience of handling, the various options of dimensions and shapes. But the dye molecules in the polymer matrix might degradate in a limited time by triplet excitation, or even destruct permanently. To avoid this shortage, WISOPTIC provides long quality guarantee period of every piece of Dye Laser Cell/Rod made in-house.

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

Cr: YAG is an excellent crystal for passive Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 and other Nd or Yb doped lasers at wavelength from 800 nm to 1200 nm. With advantages of chemical stability, durable, UV resistant, good thermal conductivity and high damage threshold (＞500 MW/cm2 ) and being easy to be operated, Cr:YAG is used widely to substitute for many traditional materials such as LiF, organic Dye and color centers.

Lithium  Niobate (LN) crystal has excellent electro-optic, acousto-optic,  piezoelectric and nonlinear properties. More and more attention has been paid on its application in military technology. LN crystal has large nonlinear optical coefficient and can easily achieve non-critical phase matching. As an E-O material, LN crystal has been used as an important optical waveguide material.

Gray Track Resistant (GTR) KTP crystals developed by hydrothermal method overcomes the common phenomenon of electrochromism of the flux-grown KTP, thus has many advantages such as high electrical resistivity, low insertion loss, low half-wave voltage, high laser damage threshold, and wide transmission band. So it's very suitable for high power density applications, where regular flux-grown KTP crystals will suffer from gray track damage.GTR-KTP crystal has gray track resistance sufficiently greater than typical flux-grown KTP.

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.

Thin film polarizers are based on interference within a dielectric optical thin-film coating on a thin glass substrate. They are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Thin film polarizers are used for polarization separation, that's to say to change un-polarized beam into linear polarized beam.

Polarization is an important characteristic of light. Polarizers are key optical elements for controlling your polarization, transmitting a desired polarization state while reflecting, absorbing or deviating the rest. There is a wide variety of polarizer designs, each with its own advantages and disadvantages.

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

Optical filters are used to selectively transmit or reject a wavelength or range of wavelengths. Their applications include fluorescence microscopy, spectroscopy, clinical chemistry, machine vision inspection, etc. Optical filters are widely used in light system of life science, imaging, industrial, or defense industries. For example, Bandpass interference filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. Notch filters reject a portion of the spectrum, while transmitting all other wavelengths.

Optical Lenses are designed to focus or diverge light and for imaging or alignment in an optical system. Optical Lenses, which may consist of a single or multiple elements, have a variety of applications. Lens forms can be divided into simple lenses (which include plano-convex lens, plano-concave lens, double-convex lens, double-concave lens, cylinder lens, drum lens, spherical lens in different shapes), achromatic lenses compound lens and multiple types.
