Mid-IR Widely Tunable OPO Source
Product information "Mid-IR Widely Tunable OPO Source"
3-5, 7.5-13 µm; Output Energy 4 µJ; Repetition Rate 0.3, 1 kHz; Pulse Width 30-50 ns; Peak Output Power 5 W, ≤100 W; Linewidth ≥100 MHz
Based on an orientation-patterned GaAs crystal, Teem Photonics’ Mid-IR, Optical Parametric Oscillator (OPO) pulsed source combines a wide spectral tunability, from 7.5 µm to 13 µm or 3 µm to 5 µm, with a very narrow linewidth down to 100 MHz. With the optional additional Optical Parametric Amplifier (OPA) stage, the source also features high peak power (100 W) and an energy of 4 µJ per pulse.
This OPO source converts the input signal from a 2 μm pump laser into a tunable Mid-IR beam using a nonlinear crystal. Its single longitudinal mode output features a kHz repetition rate and a few tens of ns of pulse duration.
One of the widely tunable OPO source’s main applications is LIDAR remote gas detection in the whole LWIR or MWIR spectral region – implemented in a LIDAR system and tested in the field, the source allowed to successfully detect different toxic gas at a distance of 300 m.
