Abstract

We present experimental results on the operation of a 1 cm diode bar-side-pumped Er:YLF laser. The mid-infrared laser produced a maximum average output power of 51 mW (102 mW peak power) for 3.1 W of chopped (50% duty cycle) pump power. When operated in true CW mode, 16 mW output power was recorded for a total pump power of 4.0 W. The centre wavelength of the spectral output of the laser was measured to be 2721 nm ± 5 nm. The threshold pump power and slope efficiency of the Er:YLF laser were measured as a function of the diode laser centre wavelength and the laser cavity length. Measurements of the spatial beam profile indicated TEM00 operation.
