        Cr:YAG crystal
            Cr: Y3Al5O12?crystal is one of the most promising passive Q-switching materials for passively Q-Switching Nd or Yb lasers at wavelength from 0.8 to 1.2um.
        • DETAIL
        • STANDARD PRODUCT
        • BASIC PROPERTIES
        • Applications:

             The preliminary experiments of Cr:YAG showed that the pulse width of passively Q-switched lasers could be as short as 9 ns for diode pumped Nd:YAG lasers and repetition rate as high as 10kHz for diode pumped Nd:YVO4 lasers. Furthermore, an efficient green output @532nm,and UV output @355nm and 266nm were generated, after a subsequent intracavity SHG in KTP or LBO, THG and 4HG in LBO and BBO for diode pumped and passive Q-switched Nd:YAG and Nd:YVO4 lasers.

           

          CRYSTIK‘s Cr:YAG is featured by:

              ●  High chemical stability and reliability. 

              ● Easy to be operation
              ● Long life time and good thermal conductivity
              ● High damage threshold (>500MW/cm2)
              ● As high power, solid state and compact passive Q-Switch

           

          CRYSTIK offers:

          CRYSTIK  provides Cr 4+ :YAG with Cr 4+ doping level from 0.5mol% to 3mol%.  The size could be from 2×2mm2 to 14×14mm2with length from 0.1mm to 12mm available.  We can control the initial transmission from 10% to 92% according to customers'  requirements.
