Master Oscillator-Power Amplifier carbon monoxide laser system emitting nanosecond pulses

To increase a peak power of carbon monoxide laser emitting nanosecond pulses a Master Oscillator-Power Amplifier (MOPA) laser system was developed. The MOPA CO-laser system employed one and the same gain medium of wide-aperture pulsed electron-beam-sustained-discharge CO-laser facility. Amplification parameters include gain and saturation intensity of amplifying media. The MOPA CO-laser system emitted a train of nanosecond pulses with peak power up to ~ 0.1 MW on a single spectral line and up to ~ 0.4 MW with multiline spectrum.     

Cascaded carbon monoxide laser frequency conversion into the 4.3-4.9 μm range in a single ZnGeP2 crystal

Collinear cascaded mid-IR frequency conversion in a single nonlinear optical crystal was accomplished. Concurrent collinear generation of the sum frequency of multiline fundamental band carbon monoxide laser radiation as a first frequency conversion cascade resulted in collinear difference frequency generation within the 4.3 to 4.9 μm spectral range when mixing this sum frequency radiation with the fundamental one as the second cascade in the same ZnGeP(2) nonlinear optical crystal.
