Abstract

In this paper we report the compression of 80 picosecond long mode-locked Nd:YAG pulses to 1.8 picoseconds by using self-phase modulation in single-mode optical fibers and a grating pair dispersive delay line. Although we generated pulses as short as 1.0 picoseconds, pulsewidths of 1.8 picoseconds were more routinely obtained. Our compressor incorporated a novel grazing incidence delay line which greatly reduced the grating separation. We achieved pulse compression ratios of 45:1 and generated visible picosecond pulses by second harmonic generation. For fixed wavelength applications the compressed cw mode-locked Nd:YAG laser provides a completely solid state source of picosecond pulses. In addition, the compressed pulses should improve the performance of synchronously pumped tunable lasers.
