Product Description
Cr 4+ :YAG
Cr 4+ :YAGcrystal 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
