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

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.

4. Experimental Result and Analysis4.2 Temperature robustness comparison between CPPLN and LBOAs a relatively new nonlinear optical material, CPPLN has a high nonlinear coefficient and a large gain bandwidth. In the foreseeable future, it will have more applications in the fields of industry and medicine. With the increasing demand for polarized crystal materials such as PPLN and CPPLN, the electric field polarization technology of crystals will also have further breakthroughs, and the processing accuracy of polarized crystals will continue to improve.

Based on the basic principles of laser damage, researchers have found a breaking through point to solve the problem of laser damage to optical components. But it is very difficult to effectively suppress the source of laser damage in the manufacturing process. Given the variety and complexity of the manufacturing process of optical components, it is necessary to establish the link between the defect formation and the manufacturing process.

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.

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.

Laser damage induced by microscopic defects in optical componentsNodule defect is a typical representative of microscopic defects, and it is one of the main discoveries in the study of laser damage to thin films in the 1990s. At present, a lot of research has been done on the electric field enhancement and damage characteristics of nodule defects and artificially implanted nodule defects. The damage mechanism of nodular defects has been deeply understood.The nodule defect is the main cause of damage to the fundamental frequency dielectric membrane element.
