Cube PBS-manufacture,factory,supplier from China

WISOPTIC is using its newly-set coating machine to do in-house vacuum coatings on crystals and optical components.With our own coating machine and technique, we can provide customers products with excellent quality, e.g. higher surface quality, higher transmittance, and higher LIDT etc.Sorts of dielectric coatings (e.g. AR, HR, PR) are available for crystals (KDP/DKDP, KTP, RTP, BBO, LBO, LN, Nd:YAG, etc) and optical components (laser windows, mirrors, PBS, etc).

It’s well known that the DKDP crystal is very easy to be damaged by humidity, especially in  environment with high temperature. So ordinary DKDP Pockels cells can not be used in high temperature and high humidity environment, or their service life is very short. After more than two years of continuous technical research, WISOPTIC has successfully developed DKDP Pockels cells that can be used in lasers working in high temperature and high humidity environments.

As the source manufacturer of many kinds of function crystals and the leading producer of DKDP Pockels cell in China, WISOPTIC provides high cost-effective products to its customers worldwide and gains substantial trust from all of its business partners. Every year over 40% of WISOPTIC's products are exported to Europe, UK, North America, Korea, Israel, etc.Normally WISOPTIC takes parts in at least one of the important exhibitions in the industry of photonics and laser, such as Laser World of Photonics (Munich/Shanghai), SPIE Photonics West (San Francisco), KIMES (Seoul), PHOTONIX (To

3 Functional laser damage evaluation and laser pretreatment technologyWhether it is microscopic defects or nanoscopic laser damage precursors, the distribution and amount in optical materials or components are closely related to the manufacturing process. Low-defect processing and manufacturing technologies have played an important role in promoting the manufacture of high-power laser materials and components. However, as the largest laser project, the ICF laser driver has the largest number and size of optical components so far.

3.3 Laser pretreatment of dielectric film with large diameter Laser pretreatment technology is the last process before the supply of large-diameter components with dielectric film in NIF devices in the United States. LLNL provides their laser pretreatment device and specifications to each of their supplier of thin film components.

After more than one year’s research work, WISOPTIC has successfully developed two types of dye laser cells – 585nm and 650nm.With advanced technique of coating and optical system design, dye laser headpiece has been developed and will be in mass production soon.Dye laser headpiece 585nm is used mainly to treat facial telangiectasia, and dye laser headpiece 650nm for removal of green tattoo, etc.Dye laser headpiece made from WISOPTIC has higher conversion efficiency than that of any competing product.

2-5 μm mid-infrared laser crystals have important applications in directional infrared countermeasures, anti-terrorism, biomedicine, environmental monitoring, optical communications, strong field physics, laser fusion, and mid-to-far infrared (nonlinear frequency conversion) basic light sources, etc. With the related development of the pump source technology of semiconductor laser (laser diode, LD), solid-state laser and fiber laser (including resonant pump), mid-infrared crystal has become one of the four main laser crystals developed currently.

1. 4  ~ 3 μm laser crystals doped with Er2+, U4+, Ho3+, Dy3+  As an active ion, Ho3+ has achieved laser output in the ~3 μm band (5I6→5I7). In 1976, researchers first realized 2.9 μm laser output in Ho:YAP crystal. In 1990, Bowman et al. obtained 2.85 μm and 2.92 μm laser outputs in Ho:YAP crystals, and obtained 2.92 μm band-tuned laser outputs in Ho:YAP crystals in the following year. In 2017, Nie et al. pumped Ho, Pr: LiLuF4 crystals with a 1 150 nm Raman fiber laser, achieving 2.95 μm watt-level laser output for the first time. In 2018, Zhang et al.

Since defects induce laser damage, and defects are randomly distributed in optical components, the detection and evaluation of laser damage performance of optical components has become another important research content. The standard for laser damage threshold testing was established in the 1990s and has been continuously improved with the development of laser technology and optical materials.

3.4 Laser pretreatment of DKDP component The laser-damaged precursor of DKDP crystals (provided by WISOPTIC) is in the material body, so it is different from the removal of surface nodule defects in dielectric films. Laser pretreatment cannot remove the precursors in the body, but can only reduce the thermodynamic response of the precursors under laser radiation by improving their absorption intensity. There are still different opinions on this mechanism.
