A Stabilized Single-Longitudinal-Mode and Wide Wavelength Tunability Erbium Laser
An erbium-doped fiber (EDF) laser with quad-ring is designed to reach the broad continuous-wave (CW) tunability and single-longitudinal-mode (SLM) behavior.

Single-longitudinal-mode optical parametric oscillator for spectroscopic applications [PDF]
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

Compound Cavity Passively Q-Switched Single-Longitudinal-Mode Diode-Pumped Laser
A compact solid-state single-longitudinal-mode (SLM) Q-switched laser based on a compound cavity is demonstrated. SLM operation is achieved through the enhancement of mode competition (via manipulation of the effective reflectivity of the resonator ...

Narrow-Strip Single-Longitudinal-Mode Laser Based on Periodic Anodes Defined by i-Line Lithography
A low-cost regrowth-free narrow-strip single-longitudinal-mode diode laser, based on periodic anodes defined only by i-line lithography is proposed. With the periodic anodes separated by surface insulated grooves acting as a 44th-order gain grating, a ...

Single-longitudinal-mode condition for DFB lasers
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.
