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.

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℃.

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

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.

Since defects induce laser damage, and defects are randomly distributed in optical components, the detection and evaluation of laser damage performance of optical components has become another important research content. The standard for laser damage threshold testing was established in the 1990s and has been continuously improved with the development of laser technology and optical materials.

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.

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.

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.

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.

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.
