FLT, 50-300 mW
Fe:ZnSe/S CW Narrow Line Tunable Mid-IR Laser
IPG's FLT is a tunable Fe:ZnSe/S continuous wave laser featuring a narrow linewidth and a cryogenic cooling system. It provides > 100 mW of output power across a 3.7 - 4.8 μm tuning range, generating >300 mW at the peak of the tuning curve. The spectral linewidth is < 1 nm with a beam mode of TEM00. The FLT laser is pumped by IPG Photonics efficient and reliable Er fiber laser. IPG’s FLT laser is used in a number of applications including pumping Mid-IR OPOs, spectroscopy, sensing, medical and defense.
