Single mode, piezoelectrically tuned, picosecond short-cavity dye laser
This letter reports a piezoelectric-translator-tuned, short-cavity picosecond dye laser. This laser, pumped by second or third harmonic picosecond pulses from a mode-locked Nd/sup +3/: glass laser, has been operated at cavity lengths which allow only a single longitudinal mode within the lasing bandwidth of a typical dye gain curve. By varying the cavity length with the piezoelectric translator, the output wavelength has been continuously tuned. With different mirror sets and dyes, the lasing output can be varied across the visible spectrum. The laser output is characterized by a modewidth of 0.3 nm (multimode) and 1.5 nm (single mode). The energy conversion efficiency was found to be roughly 0.3% for single-mode operation and >3% for multimode operation at 600 nm.
