Diffusion bonded
Cr:YAG+Nd:YAG Rod
The diffusion bonded Cr:YAG+Nd:YAG Rod consists of one Nd:YAG crystal and one or two Cr:YAG absorber. They are combined by optical contact method and further bonded under high temperature. The diffusion bonded Cr:YAG+Nd:YAG Rod helps to decrease thermal lens effect considerably in high power solid state Laser.
Features
★ Improve beam quality
★ High damage threshold
★ Decrease thermal effect
★ Improve efficiency
★ Compact size
