Popis:	Experimental results are presented giving the operating characteristics of a newly developed DF–CO2 purely chemical laser. The present oscillator is capable of a maximum cw output power of 162 W at 10.6 μ with no external energy source used to initiate or sustain laser excitation. An optical axis has been employed aligned transverse to the flow direction with a view toward achieving operation which can be directly scaled to high output powers. Measurements of saturation parameter, unsaturated gain coefficients, and vibration‐rotation state populations for P‐ and R‐branch CO2 (00°1) → CO2 (10°0) transitions, power output, operating temperatures and pressures, and chemical efficiency are presented.
