FLPM and FLPMT 200 μs, >400 mJ

Fe:ZnSe/S Microsecond Pulsed Laser

FLPM and FLPMT are Fe:ZnSe/S pulsed free-running cryogenically-cooled lasers. Users can select a fixed wavelength within a 3.9 - 5.0 μm range with the FLPM model, or choose a wavelength tunable FLPMT model. The lasers provide 200 μs pulses with pulse energy up to 400 mJ and output power up to 35 W. The repetition rate is from a single pulse up to 100 Hz; the spectral linewidth is < 1 nm. FLPM/FLPMT lasers are pumped by built-in flashlamp-pumped Er:YAG operating at 2940 nm. The FLPM and FLPMT lasers are used in applications such as Mid-IR sensing and active thermal imaging.
