KTP, BBO, KD*P Pockels Cell Driver-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.

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

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).

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.

Introduction High-power all-solid-state deep ultraviolet (DUV) lasers have many important applications in scientific research, medical diagnosis, and industrial manufacturing, such as Raman spectroscopy, photobioimaging, integrated circuit etching, and precision micromachining, due to their compact structure, high single-photon energy, and good long-term stability.

Experimental SetupIn order to obtain a 266 nm deep ultraviolet laser with high efficiency and stable operation, this paper built an all-solid-state 266 nm deep ultraviolet laser generation device as shown in Figure 1, which consists of a cavity-dumped all-solid-state Nd:YVO4 laser, a double-frequency system, and a quadruple-frequency system.Fig.

03 Experimental results and analysisBy optimizing the cavity length parameters of Nd:YVO4 (www.wisoptic.com) laser under high-power pump injection, a 1064 nm high peak power narrow pulse laser output with an average power of 26 W, a repetition frequency of 20 kHz, and a single pulse width of 5 ns was obtained when the 888 nm pump light power was 65 W; after the 1064 nm fundamental frequency infrared light was doubled by the LBO crystal, a 532 nm laser with a maximum power of 16 W was finally obtained, and the infrared to green light conversion efficiency reached 61.5%.

3 The main application of lithium tantalate crystal3.3 E-O Q-SwitchThe basis of laser Q-switched technology is a special optical component - a fast intracavity optical switch generally called Q-switch. The Q value is an indicator for evaluating the quality of the optical resonant cavity. The higher the Q value, the lower the required pump threshold and the easier it is for the laser to oscillate. The purpose of laser Q-switching technology is to compress the pulse width and increase the peak power.

1.3 Doping of Lithium Tantalate CrystalDifferent fields have different requirements for the properties of lithium tantalate crystals. When being used to prepare high-density and large-capacity holographic information storage devices, LiTaO3 crystals need to have excellent photorefractive properties. Due to the particularity of the crystal structure of LiTaO3, its physical properties can be adjusted through doping, for example, the widely used photorefractive doping.

The variant of refractive indices with temperature is an essential crystal parameter in nonlinear optics. it is well known that the wavelength at which 90° phase-matched 2nd-harmonic era happens depends on temperature. the variation of this wavelength with temperature can be predicted with a understanding of the variant of the refractive indices with temperature and is cited on this paper because the tuning price.
