Custom Laser Crystals for Solid-State Laser Systems
ATR Crystal supplies laser crystals and optical crystals for diode-pumped solid-state lasers, Q-switched lasers, ultrafast lasers, medical lasers, industrial laser sources, research laser cavities, and photonics systems. The correct crystal depends on wavelength, gain, pump source, thermal load, pulse format, coating, and cavity design.

Laser Design Considerations
- Target wavelength and output format
- Diode, lamp, or other pump source
- Doping level, orientation, and crystal dimensions
- Thermal conductivity, thermal lensing, and cooling design
- AR, HR, or custom coating specifications
- Damage threshold, surface quality, wavefront distortion, and parallelism

Frequently Asked Questions
What is the difference between Nd:YAG and Nd:YVO4?
Nd:YAG is a mature and robust gain medium for many laser formats. Nd:YVO4 offers high absorption and gain for compact diode-pumped systems but requires application-specific thermal and cavity design review.
When should I choose Cr:YAG?
Cr:YAG is used as a passive Q-switch, not as the main gain crystal. It can simplify compact pulsed laser designs around the 1.0 to 1.2 um range.
Can ATR Crystal supply coated laser crystals?
Yes. AR, HR, and custom coatings can be discussed when wavelength, reflectivity, damage threshold, and operating conditions are defined.
