Abstract

Tm:Ho:YLF, operating single frequency at 2.055 μm, provides a viable transmitter for developing eyesafe, Doppler-based remote wind-sensing instruments.^1,2 The spectroscopic and thermal properties of Tm:Ho:YLF combine to provide an efficient, near-room- temperature, all-solid-state laser.³ The laser is configured as a cw master oscillator injection- seeding a pulsed-pumped-power oscillator, (Fig. 1). The master oscillator provides the needed cw local oscillator and serves as the probe to sense power-oscillator axial mode matching. Single-longitudinal-mode operation has been demonstrated by synchronizing power-oscillator Q-switching with axial mode matching to the master oscillator. The mode-matching condition is repetitively scanned by using a PZT-actuated mirror in the power oscillator.
