Paper Abstract

We report a pulsed, Nd:YAG (1064 nm) microchip laser amplified by a mode-filtered, Yb-doped fiber amplifier. The system provided a widely tunable repetition rate (7.1-27 kHz) with constant pulse duration (1.0 ns), pulse energy up to 0.41 mJ, linear output polarization, diffraction-limited beam quality, and <1% pulse-energy fluctuations. Detailed spectral and temporal characterization of the output pulses revealed the effects of four-wave mixing and stimulated Raman scattering, and we investigated the effects of fiber length and Yb-doping level on system performance. The amplifier output was efficiently converted to a variety of wavelengths between 213 and 4400 nm by harmonic generation and optical parametric generation, with Watt-level output powers. The laser system employs a simple architecture and is therefore suitable for use in practical applications.
