title: Single-frequency, thin-film-tuned, 0.6-W, diode-pumped Nd:YVO(4) laser.
abstract: Application of a metallic thin-film selector to the single-frequency oscillation of a diode-pumped Nd:YVO(4) laser has been investigated theoretically and experimentally. We show that a chromium thin-film selector with a thickness between 8 and 9 nm provides single-frequency output within a power range of 0.6 W. Single-frequency operation, slow smooth tuning, or chirping was realized by the output coupler movement with a piezoceramic transducer. Chirping at a repetition rate of 0.5 kHz in the 0.5-10-GHz range was achieved. Physical and technical limitations caused by the wide-gain bandwidth, thermal effects, and mechanical vibrations of cavity elements are discussed.
