Altechna has unveiled new Cr LiCAF, LiSGaF and LiSAF laser crystals that have been manufactured using the Czochralski method.
The company utilizes starting materials to enable crystal growth and absorption spectroscopy to measure dopant concentration.
The Cr3+:LiSrAlF6 (Cr:LiSAF) colquiriite crystal is a vibronic laser medium that supports femtosecond pulses and generates pulses with a minimum of 24 fs duration. The Cr-doped colquiriite crystal is tunable in the 780-1010 nm near-IR range.
The crystal lasers utilize red pump source instead of a green pump and due to this, they are more cost-effective than titanium - sapphire lasers. The colquiriite crystal lasers can be used with low pump powers, enabling diode pumping to be feasible.
