Pockels Cells-manufacture,factory,supplier from China

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.

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.

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

Study on the efficiency and temperature robustness of chirped PPLN crystal in 1064nm frequency doubling experiment - 06  4. Experimental Result and Analysis4.2 Temperature robustness comparison between CPPLN and LBOWhen the input 1064nm light is 22.53W, the curves of the frequency-doubled optical power generated by CPPLN (www.wisoptic.com) and LBO (www.wisoptic.com) with temperature are shown in Figure 5(a) and Figure 5(b). The half-maximum full width of the frequency-doubled optical power of CPPLN with respect to temperature is 8.40℃, ranging from 24.19℃ to 32.59℃.

3 The main application of lithium tantalate crystal3.1 SAW Wave filterYang Qing-rui and others designed a resonator SAW filter using LiTaO3/SiO2/Si substrate. Figures 3 and 4 are optical photos of the device and partial scanning electron microscopy pictures of the device respectively. The interdigitated electrodes of the device in the picture are clear and no adhesion is seen.

1. ~ 2 μm laser crystals doped with Tm3+ or Ho3+Tm3+ has a strong absorption near ~790 nm and a large absorption cross-section, so the ~790 nm commercial LD can be directly used as a pump source.

IntroductionLithium tantalate (LiTaO3, referred to as LT), as an excellent multifunctional crystal material, has good piezoelectric, electro-optical and pyroelectric properties, and is ideal for making surface acoustic wave (SAW) filters, resonators, tuners, Q switches and pyroelectric detectors. Devices made from LT crystal (www.wisoptic.com) are widely used in the automotive electronics, 5G communications and infrared detectors, and have broad market prospects.In 1965, Ballman used the pulling method to grow LT single crystal for the first time.

Nanoscale laser damage precursorsDifferent from microscopic defects, defects are called precursors here. Defects generally refer to observable microstructures that are different from the characteristics of the surrounding matrix materials, and are often observed by optical microscopy. The precursors mentioned in this article generally cannot be directly observed by optical methods, and there is no obvious difference in characteristics from the surrounding matrix materials.

Laser damage induced by microscopic defects in optical componentsAccording to the above numerical analysis results, it can be seen that cracks may be generated around the nodule seed and propagate along the radial direction.
