Er: YAG Crystal

Er: YAG crystal, likewise referred to as erbium-doped yttrium aluminum garnet, with the chemical formula Er: Y3Al5O12, is a well-integrated laser crystal currently commonly made use of in the clinical field fields. Er: YAG crystal is based upon YAG crystal as well as Er3+ ions as doping ions. It comes from the cubic crystal system and is one of the laser crystals that work at room temperature.

Er: YAG crystal has an abundant energy level structure and also great laser performance. It can stably send out lasers with wavelengths of 1.64 μm, 1.78 μm, and also 2.94 μm, permitting high-concentration ion doping, and the power degree lifetime of the laser decreases when high doping is used. Little, the laser performance is boosted. The 2.94 μm emission wavelength of Er: YAG with a doping focus of 50% is located at the water absorption optimal, which can be highly soaked up by water molecules as well as can also be absorbed by biological cells. Since the absorption coefficient of water at this wavelength is 100 times larger than that of 2 μm as well as 10,000 times larger than 1 μm, the 2.9 μm laser word has essential applications in the clinical area. Er: YAG crystals have been made use of in medicine, such as dental surgery, plastic surgery, and ophthalmology. And also Er-YAG laser wavelengths can boost numerous skin problem, such as actinic photodamage, hyperpigmentation, stressful scarring, rough skin texture, laxity, and so on. Additionally, with the advancement of laser modern technology, ¬ Er: YAG pump lasers additionally have applications in the military field as well as melon optical communication, such as lidar, telemetry, and energetic imaging.

In the context of the constant growth of the laser sector, the Er: YAG crystal market room is additionally increasing. Presently, foreign firms generating crystals mostly consist of Fabrinet in the UK, Optogama in Lithuania, Lasertec in Japan, etc; residential firms mainly consist of Fujing Modern technology, Jabil Skyway, Hengguang Optoelectronics, Nanjing Lite-On, Jingyuan Optoelectronics, etc.

Pockels Cells Crystal

1. Pockels Cells Based on the electro-optic effect , when the applied electric area acts on the Pockels cell crystal ( electro-optic crystal ), the Pockels cell crystal (electro-optic crystal) is like a wave plate whose phase delay is related to the used electric field. The polarization state of the outbound light from the Pockels cell crystal will certainly change so that the strength as well as amplitude of the outbound light from the analyzer are regulated, which is electro-optic inflection, and the modulation tool is called a Pockels cell. 2. Pockels cell crystal The crystals that produce the electro-optical effect are called Pockels cell crystals, that is, electro-optical crystals. They each have their benefits. Presently, the major Pockels cell crystals on the marketplace consist of BBO crystals , DKDP crystals , KTP crystals , as well as LN (LiNbO3) crystals . (1) BBO crystal BBO crystal , additionally called barium metaborate crystal, chemical formula BaB2O4, is an electro-opt

  YCOB nonlinear crystal – Laser Crylink laser crylink Description YCOB crystal is one of the most widely used nonlinear optical crystals. Its nonlinear optical coefficient is equivalent to that of BBO crystal and LBO crystal. The effective frequency multiplication coefficients of the second and third order reach 2, 8 and 1, 4 times of KDP respectively. The YCOB crystal has the following advantages : large aperture, high damage intensity in femtosecond regime,about2000-2500GW/cm2 wide allowable Angle range and allowable temperature range, small dispersion Angle, shorter growth period by Cz method. At the same time, it has stable physical and chemical properties (non-deliquescent) and good machining properties. Therefore, it is considered to have good application prospects of blue-green light and UV band optical frequency multiplier crystal. Feature · Electric resistivity is high · Temperature acceptance is high · Laser induce damage threshold is high · Less anisotropy · Thermal expansi

Neodymium doped yttrium vanadate (Nd: YVO4) is a kind of laser crystal extensively utilized at present. It has superb efficiency as well as is among the major laser crystals for semiconductor pumped solid state lasers today. Nd: YVO4 crystal is a tetragonal crystal, belonging to the uniaxial crystal system, which is composed of doped ion Nd and also laser matrix YVO4. Compared to another frequently utilized Nd: YAG crystal, Nd: YVO4 has the advantage of higher absorption coefficient. In a specific variety of absorption transmission capacity, the absorption effectiveness of Nd: YVO4 is 5 times that of Nd: YAG, the transmission capacity is 2.4-6.3 times that of Nd: YAG, as well as the peak wavelength of the absorption top is reached at concerning 808nm, which has satisfied the requirements of present high-power laser diodes. The boosted sample of Nd: YVO4 at 1064nm and also 1342nm are bigger, and also the boosted random sample of Nd: YAG at 1064nm have to do with 3 times that of Nd: YAG
