Abstract

We constructed a cw Ti:Al₂O₃ master oscillator–dye preamplifier–Ti:Al₂O₃ power amplifier system that generates <2-ns, 100-mJ pulses. The system is tunable from 750 to 890 nm and has a repetition rate of 30 Hz. The output pulse has a near Fourier-transform-limited bandwidth of ∼240 MHz. Backward stimulated Brillouin scattering is used to control the growth of amplified spontaneous emission (ASE). The content of ASE in the final output is under our detection limit (<10^-4) for the entire tuning range.
