A tunable optically pumped HBr laser has been demonstrated for the first time. As pump source for the HBr oscillator, we developed a single-frequency Ho:YLF laser- amplifier system which was locked to the 2064 nm absorption line of HBr. Through the implementation of an intra-cavity diffraction grating, laser oscillation was demonstrated on nineteen molecular transition lines including both the R-branch (3870 nm to 4015 nm) and the P-branch (4070 nm to 4453 nm). The highest output energy for the given input energy was 2.4 mJ at 4133 nm.
