RTP Pockels Cell-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

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).

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%.

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

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.

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.

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.

IntroductionLithium tantalate (LiTaO3, referred to as LT), as an excellent multifunctional crystal material, has good piezoelectric, electro-optical and pyroelectric properties, and is ideal for making surface acoustic wave (SAW) filters, resonators, tuners, Q switches and pyroelectric detectors. Devices made from LT crystal (www.wisoptic.com) are widely used in the automotive electronics, 5G communications and infrared detectors, and have broad market prospects.In 1965, Ballman used the pulling method to grow LT single crystal for the first time.

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.
