The construction and operation of a long pulse, single-mode Nd:YAG laser is described. The laser is configured around an injection-seeded, unstable oscillator/single amplifier and produces 80 ns pulses at 10 Hz with pulse energies of over 300 mJ. When frequency doubled, the infrared is converted to a 56 ns pulse at 532 nm with a Fourier-limited linewidth of 8 MHz. This approach brings the Nd:YAG source to within the bandwidth domain normally dominated by visible CW lasers, but at a considerably higher power, thus providing an attractive alternative for applications in high resolution spectroscopy and non-linear studies.
