Stable Chemical Properties Cr4+:YAG Laser Crystals
Products Description:
The preliminary experiments of Cr:YAG Crystals 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. Laser Crystal Chromium Doped Yttrium Aluminum Garnet Crystal (Cr4+:YAG) is an excellent crystal for Q-switches application.
Crystrong provides Cr4+:YAG with Cr4+ doping level from 0.5mol% to 3mol%. The size could be from 2×2mm2 to 14×14mm2 with length from 0.1mm to 12mm available. We can control the initial transmission according to customers ‘requirements.
Cr4+:YAG is also a laser crystal with tunable output from 1.35 µm to 1.55 µm. It can generate ultrashort Pulse Laser (to fs pulsed) when pumped by Nd:YAG laser at 1.064 µm.
