Product Description
Triple doped Cr3+,Tm3+, Ho3+:YAG is an efficient solid-state laser medium for 2097nm generation, widely used in military, medicine, and remote sensing applications. High spectral overlap of pump radiation (lamp or diode) with the Cr3+ and Tm3+ absorption bands, and a highly efficient conversion from the absorption bands into the 5I7 -> 5I8 Ho3+ emission band, enables 2 micron laser architectures with high quantum efficiency.
DJ-LASER provides high quality CTH:YAG for your prouction and/or development efforts.CTH:YAG is applied for both lamp bumping laser and LD pump laser, widely used in the field of medical lasers.
Advantage
High slope efficiency
May be flash lamp or diode pumped
Operates well at room temperature
Operates in a relatively eye-safe wavelength range
