Cryogenic adsorption technique may replace machinery pump and exhaust processing system, hence nitrogen dilution is used in discharge-driven continuous wave(CW) HF/DF chemical laser, which can greatly reduce the size and weight of laser system. The gain distribution of supersonic discharge-driven CW HF chemical laser is measured by small signal gain measurement system. Gain distribution curves of P1(4), P1(6), P2(4), P2(5), P2(6) are obtained at four different laser power, and the highest gain spectral line is P2(4) with the highest gain of 0.1 cm-1. The position of the highest gain is just the best position of optical axis. Under supersonic air stream, the gain zone extends to 2.5 cm.
