  • Nd Yvo4 Crystal Lens - China

    price: contact company for price

    Nd: YVO4 crystal is one of the most excellent laser host materials, it

    is suitable for diode laser- pumped solid state laser. The crystal has

    these main features: low lasing threshold, high slope efficiency, large

    stimulated emission cross- section, high absorption over a wide pumping

    wavelength bandwidth, easy tuning for single mode and high tolerance for

    pumping wavelength. Recent developments have shown that Nd: YVO4 micro-

    lasers can produce powerful and stable IR and green or red laser with

    the design of Nd: YVO4+KTP.
