Description:
<jats:p>The construction and performance of a small-scale cw HF(DF) chemical laser is described. A multiline output of about 15 W was achieved. During single-line operation, 18 HF 2-1 and 1-0 transition lines, with powers from 0.1 to 2.4 W, and 24 DF 3-2, 2-1, and 1-0 transition lines, with powers from 0.01 to 0.30 W, were observed. Amplitude stability varied from ±1.5 to ±5%, and free-running short-term frequency stability was about ±10 MHz.</jats:p>
