Abstract

An optically pumped tunable HBr laser has been demonstrated for the first time. The pump source was a single-frequency Ho:YLF laser and amplifier system, which was locked to the 2064 nm absorption line of HBr. Laser oscillation was demonstrated on 19 molecular transition lines, which included both the R-branch (3870–4015 nm) and the P-branch (4070–4453 nm), by the use of an intra-cavity diffraction grating. The highest output energy was 2.4 mJ at 4133 nm.

Schematic depicting pumping and lasing transitions of a 2 μm pumped HBr laser. Pumping is from the ground vibrational level v=0 to the v=2 vibrational level. Lasing can occur on various P-branch (J=J+1) and R-branch (J=J1) transitions from v=2 to v=1. After lasing, the remaining excited vibrational levels eventually relax back to v=0 through vibration-to-translation (V–T) processes, which release heat into the gas.

Atmospheric transmission in the 3.6–5 μm region (from space to ground at an altitude of 4.2 km) using the program IRTRANS4 [9] with the emission cross sections of v=2 to v=1 transitions of HBr [3] superimposed upon it. The cross sections have been normalized such that the strongest line, P(4), equals 100%.
