Product Description
  • Product name: Imports YAG laserYAG Series Crystals

    Nd:YAG crystal:

    Nd:YAG crystal is the most excellent comprehensive properties of laser crystal, laser wavelength 1064nm, widely used in military, industrial and medical industries.

    Ce:Nd:YAG crystal

    The laser pumped by flashlamp pumped light emission spectrum, is actually a broadband continuous Pu, only a few of the spectral peak and Nd ion absorption peak matching, so the general use of lamp pumped only rarely part of the energy spectrum, the efficiency is low. Adding Ce ions in Nd:YAG crystal is formed on the basis of Ce:Nd:YAG the ultraviolet spectral region of photon energy absorbing good use of the Ce ion, and the energy in the non radiative transition way to Nd ions, thus increasing the spectrum utilization rate, so the laser rod with high efficiency, low threshold, repetition frequency characteristic is good. In addition, it will be harmful to the purple Nd:YAG external radiation (ultraviolet radiation, long time will be the formation of color centers in Nd:YAG crystal, thereby reducing the laser properties of the crystals) for effective use, therefore, anti ultraviolet radiation, even without the use of special UV filter quartz sleeve .Ce:Nd:YAG Ce because of the crystal doped after the crystal was yellow, so called yellow rods. Can provide F1-20 (D) ´ 10-140 (L) mm laser rods and various kinds of slab elements, Nd concentration of 0.6 ~ Ce, 1.1at.% concentration of 0.03 ~ 0.4at.%.

    Yb:YAG crystal

    Yb:YAG is a trivalent ytterbium ion (Yb3+) doped yttrium aluminum garnet (YAG) laser crystal matrix formed in a 1.03um near infrared laser, and Nd:YAG belong to the same kind of matrix, but due to different doping caused the growth process is different. Because of high quantum efficiency of ytterbium doped YAG (91%), crystal spectrum simple, no excited state absorption and upconversion fluorescence, and no concentration quenching, high doping concentration (up to 30at.%), a long fluorescence lifetime (0.91ms), the absorption band (18NM) than Nd:YAG (<4nm) is much wider, can pump wavelength and effective coupling diode in the same input power. Under Yb:YAG pumping heat is only Nd:YAG 1/4. and performance characteristics of YAG matrix material is the most excellent, so Yb:YAG has become one of the most striking solid laser medium, Yb:YAG high power LD pumped solid state laser has become a new hotspot, and regards it as a The development of high efficiency, high power solid-state laser is one of the main directions.

    Industrial laser equipment such as laser marking machine, laser engraving machine, laser welding machine, laser scribing machine, laser engraving machine, laser drilling machine is the use of Nd:YAG laser rod.

    Ce:YAG phosphor

    Ce:YAG fluorescent powder is the main industrial production of phosphor white LED. Method of making white LED is usually with high performance InGaN/GaN based blue LEDs emits blue light excitation YAG:Ce rare earth phosphor, YAG is excited and emit yellow light and blue light mixed into white light. The remaining white LED technology for the rational use of energy, alleviate the energy crisis and green has important significance lighting. The main synthesis methods are: high temperature solid phase reaction method, sol-gel method, spray pyrolysis method, co precipitation method.
