Product Description
Cr4+:YAG
Cr 4+ :YAG crystal is excellent passive Q-switched crystal widely used in 1μm neodymium and ytterbium lasers. It has the characteristics of high output efficiency of Q switch and suitable for repetitive frequency work. It has a high resistance to photodamage threshold, is more stable and durable than dyes and color center saturable absorbers, and can replace electro-optic Q switches to output high-power laser pulses in some cases. Chromium doped yttrium aluminum garnet (Cr 4+ : YAG) Cr: Y 3 Al 5 O 12 crystal It is suitable for Q switch, diode pumping, Nd:YAG, Nd:YLF, Nd:YVO 4 pumping lamps and others Lasers with a wavelength of 0.8~1.2um doped with Nd or Yb. Main features: High chemical stability and reliability long life Good thermal conductivity High damage threshold (>500MW/cm 2 ) Available as a high power, solid state and compact passive Q-switched switch easy to operate
