Right Angle Prism-manufacture,factory,supplier from China

MEASUREMENT TECHNIQUEThe measurement technique consists primarily of a measurement of the variation of the angle of deviation with temperature. The crystals to be measured were 60-60-60° prisms approximately 15 mm on a side. They were attached to a temperature-controlled mount in a vacuum chamber. The temperature could be varied by varying the temperature of a liquid bath above the mount. Temperature was measured by thermocouples attached above and below the crystal. The crystal temperature was assumed to be the average of the two temperatures.

03 Experimental results and analysisWhen the green light input power is lower than 4 W, the matching temperature of the BBO crystal has little effect on the output power of the quadrupled 266 nm laser, and when the optimal power of ultraviolet light output is achieved, the temperature offset ΔT of the heating device also tends to be consistent; when the green light input power is greater than 8 W, the higher the matching temperature of the BBO crystal (www.wisoptic.com), the smaller the temperature offset ΔT of the heating device, and the higher the output power of the 266 nm la

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.

In 1962, the American scientist McClung F J reported for the first time that the silver mirror of the ruby laser resonator had hole burning damage, which was the first public report on the laser damage of optical components. The subsequent invention of Q-switching technology and mode-locking technology increased the peak power of laser pulses by several orders of magnitude. The problem of laser damage runs through and affects the design and operation of lasers, and promotes the development of optical materials and optical component manufacturing technologies.

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.

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.

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.

The Asia Photonics Expo (APE) is a holistic photonics platform for branding and business connection, focusing on the latest cutting-edge innovative technologies and the emerging application markets in Asia, aiming to promote the in-depth communication and business collaboration between photonics upstream and downstream professionals.WISOPTIC will show its hot products supplying to the  whole world (EU, USA, UK, Asia, etc.) and looking forward to meeting new friends as well as its "old" business partners all over the world.
