Abstract
Cw mode-locked Nd:YAG and Nd:YLF lasers have been the standard sources for the generation of picosecond optical pulses for many years. More recently, diode-laser pumping and passive mode-locking of these lasers using semiconductor saturable absorbers has been shown to produce pulse durations down to the sub-ps range with exceptional stability and insensitivity to variations in cavity length. A special property of Nd:YLF as compared to Nd:YAG is that it oscillates at two wavelengths, 1047 and 1053 nm, the latter of which matches the wavelength of maximum gain in Nd-doped phosphate glasses. Here we report on mode-locked operation of a diode-laser-pumped Nd:YLF laser at 1053 nm using a saturable Bragg reflector (SBR).
