N2 - We demonstrated a high energy delivery of a pulsed wavelength-selected HF chemical laser by fluoride glass fibers (core/cladding=450/500 μm). The optical energy of 19 mJ in a 540 ns pulse was successfully delivered with a peak intensity of 22 MW/cm2 at the exit core surface. We have also theoretically investigated the operational characteristics of the pulsed chain first vibrational overtone HF chemical laser using a computer code. The model used can describe simultaneously both the fundamental and overtone oscillations. The higher overtone output energy of 2.73 J/1 can be obtained with a gas mixture consisting of F2/H2/He=10/4/786 (Torr) by successfully suppressing the ASE.
