Product Description

Cr:YAG crystals are exceptional passive Q-switching elements for 1 μm neodymium and ytterbium lasers. These crystals exhibit high Q-switching efficiency and are well-suited for high repetition rate operation. With a high damage threshold, they offer superior stability and durability compared to dye and color center saturable absorbers, making them a viable alternative to electro-optic Q-switches for high-power pulsed laser output in certain applications.
