Frequently Asked Questions

Low-doped Er:YAP laser crystals are used for the production of eye-safe radiation at 1,66 microns by in-band pumping with semiconductor laser diodes at 1,5 microns.

Er:YAP crystals with high doping concentration of Er3+ ions are typically used for lasing at 2,73 microns, which is advantageous due to its natural birefringence combined with good thermal and mechanical properties similar to those of YAG.

The advantage of using low-doped Er:YAP laser crystals is low thermal load corresponding to low quantum defect.

The wavelength of the eye-safe radiation produced by low-doped Er:YAP laser crystals is 1,66 microns.

YAP stands for yttrium aluminium oxide, which is a laser host for erbium ions.
