Ho:Cr:Tm:YAG (CTH:YAG) Laser Crystal, 2.1μm Eye-Safe, High Efficiency Flash/Diode Pumped
Ho:Cr:Tm:YAG (CTH:YAG) Laser Crystal, 2.1μm Eye-Safe, High Efficiency Flash/Diode Pumped
Cr:Tm:Ho:YAG crystals are laser crystals that use yttrium aluminum garnet (YAG) as an activator medium, incorporating sensitizing ions chromium (Cr), energy-transfer ions thulium (Tm), and activator ions holmium (Ho). These crystals produce laser light of specific wavelengths through pulse solid-state laser devices and are widely used in various fields.
