Single-longitudinal-mode optical parametric oscillator for spectroscopic applications [PDF]
Optics Letters, 2002 We have developed a tunable, narrow-bandwidth nanosecond optical parametric oscillator system and applied it to spectroscopic studies. The system consists of a narrow-bandwidth grazing-incidence oscillator and a seeded power oscillator, generating Fourier-transform-limited 1.5-ns pulses (bandwidth

Single-longitudinal-mode condition for DFB lasers
Electronics Letters, 1985 We show theoretically that the loss difference of about 10% is required between the main mode and the side mode for a semiconductor laser to oscillate in single-longitudinal mode. The DFB laser has been found to meet this requirement, and a side-mode suppression of more than 30 dB was observed under high-speed direct modulation.
