Good Quality Ktp - Fe:ZnSe – Dien

Fe²+:ZnSe and Fe²+:ZnS saturable absorbers (SA) are ideal materials for passive Q-switches of solid-state lasers operating in the spectral range of 2.5-4.0 μm.

These lasers (e.g. 3.0 μm Er:YAG/YSGG/YLF) are used for pumping middle-infrared Optical Parametric Oscillators and for numerous medical and dental applications.
Applications:

• As a gain material in compact laser systems;
• As passive Q-switch for 2800 – 3400 nm nm lasers;
• Source for pumping middle infrared (MIR) optical parametric oscillators (OPO);
• Spectroscopy;
• Infrared (IR) missile countermeasure systems (ship and aircraft based);
• Free space communications;
• Gas tracing and analysis;
• Chemical warfare detection;
• Non-invasive medical diagnostics;
• Medical surgeries;
• Cavity ring down (CRD) spectroscopy
