The design and construction of a pressure tuned single longitudinal mode (SLM) dye oscillator is described. The oscillator had a pressure tuned range of ⩾ 3.75 cm−1 and a time average linewidth of 0.019 cm-1. The output of the oscillator could be increased by four orders of magnitude in an amplifier chain which incorporated a phase conjugate reflector to control the build up of amplified spontaneous emission. Focusable power of > 100 GW/cm2 were obtained at a linewidth of 0.022 cm-1.
