When coming to sourcing a Cr4＋:YAG Q Switch for yoUr Nd: YAG ROD there are 2 parameters to be considered:
how to keep the initial transmission T0 value fixed and most important maintain high energy output that happens to be very sensitive to the location in the crystal boule.
Arsuf lasers manufacturing process takes care of these specs.
A high level of polishing and our hard coating process complete the production cycle.
Arsuf lasers also provides engineering support and failure analysis free if needed.

Cr4+:YAG (Yttrium Aluminum Garnet doped with Chromium ions) is a laser crystal that is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd: YAG, Nd: YLF, Nd: YVO4 or other Nd and Yb doped lasers at a wavelength from 0.8 to 1.2 µm. It is an Excellent crystal for high repetition rate electro-optical applications and can handle high power pulses and get to a fairly high laser damage threshold. material is not hygroscopic and with a High extinction ratio
. The Cr4+ ions in the crystal act as an active laser medium, while the YAG crystal matrix provides mechanical stability and high thermal conductivity. The Q-switch, also known as a mode locker, is an optical switch that controls the build-up and release of laser energy within the cavity, allowing for the generation of high-energy, short-pulse laser beams. This type of laser is widely used in medical, industrial, and scientific applications such as laser cutting, laser welding, and laser marking.
