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%.

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℃.

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.

2.1 Manipulating and understanding laser damage precursors through material growth processesCombined with the statistical model, information such as precursor density and threshold distribution can be extracted from the damage probability curve, which indirectly reflects the information of the precursor. The analysis shows that the KDP crystal (www.wisoptic.com) mainly contains a precursor with a threshold distribution.

1.5  ~ 4 μm laser crystals doped with Fe2+ Compared with Cr:ZnSe, Fe:ZnSe has a smaller band gap and is prone to produce thermally induced multi-phonon quenching, so both laser power and efficiency are low. In 1999, Adams et al. realized the tunable wavelength of 3.98-4.54 μm at low temperature for the first time in Fe:ZnSe, and obtained laser output with slope efficiency of 8.2%. Pumped by Er3+ doped or Cr:ZnSe @ 2.7 μm laser, 4.0 μm wavelength and 1 W level continuous laser output have been obtained at room temperature. In 2020, Pushkin et al.

3 The main application of lithium tantalate crystal3.4 Pyroelectric detectorTo detect targets, pyroelectric detectors generally exchange heat with the outside environment through three methods: thermal convection, thermal conduction and thermal radiation. The working principle is: electrons are adsorbed on the surface of the pyroelectric material, and the surface is neutral; the temperature of the material surface changes when heated, and the electric dipole moment of the material changes; in order to keep the surface of the material neutral, the surface releases charges.

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.

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.

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

Introduction 532nm solid-state lasers are widely used in industry and medicine. In the field of scientific research, continuous, high-stability 532nm green light and kilohertz, high-energy nanosecond 532nm laser are the most ideal pump source solutions for titanium sapphire oscillators and amplifiers respectively. The basic route is to use an 808nm/880nm semiconductor laser as the pump source, generate a 1064nm laser in an Nd:YVO4 or Nd:YAG crystal, and then perform frequency doubling (SHG) through a frequency doubling crystal to generate a continuous or pulsed 532nm laser.
