Periodically Poled KTP-manufacture,factory,supplier from China

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).

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.

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.

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 crystal3.1 SAW Wave filterThere are many studies on filters in SAW devices. Wave filters have the advantages of low transmission loss, high reliability, great manufacturing flexibility, analog/digital compatibility, excellent frequency selection characteristics, and can realize a variety of complex functions.

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

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.

3 The main application of lithium tantalate crystal3.1 SAW Wave filterYang Qing-rui and others designed a resonator SAW filter using LiTaO3/SiO2/Si substrate. Figures 3 and 4 are optical photos of the device and partial scanning electron microscopy pictures of the device respectively. The interdigitated electrodes of the device in the picture are clear and no adhesion is seen.

2-5 μm mid-infrared laser crystals have important applications in directional infrared countermeasures, anti-terrorism, biomedicine, environmental monitoring, optical communications, strong field physics, laser fusion, and mid-to-far infrared (nonlinear frequency conversion) basic light sources, etc. With the related development of the pump source technology of semiconductor laser (laser diode, LD), solid-state laser and fiber laser (including resonant pump), mid-infrared crystal has become one of the four main laser crystals developed currently.
