III Single-Longitudinal-Mode Semiconductor Lasers

1988
Publisher Summary This chapter discusses the single-longitudinal-mode (SLM) semiconductor lasers. The use of single-mode fibers has eliminated the problem of modal noise. The chapter reviews the recent progress in the field of SLM semiconductor lasers. The physics of semiconductor lasers is discussed and the material system and the structure commonly

RTP Q-switched single-longitudinal-mode Nd:YAG laser with a twisted-mode cavity

Applied Optics, 2015
This paper describes a high pulse repetition frequency Nd:YAG twisted-mode laser that uses an RTP crystal as the electro-optic Q-switch. Stable single-longitudinal-mode laser beams at 1, 5, and 10 kHz were obtained with a linewidth less than 0.1 GHz.

Tunable, Single-Longitudinal Mode 2 μm VECSEL

Frontiers in Optics + Laser Science APS/DLS, 2019
A tunable, 2 μm, narrow linewidth vertical-external-cavity surface-emitting laser (VECSEL) is demonstrated. Single-longitudinal mode operation with sub-MHz linewidth is achieved over a tuning range of 80 nm.

Partition fluctuations in nearly single-longitudinal-mode lasers

Journal of Lightwave Technology, 1984
A simple model of mode partition noise is developed, which is valid for semiconductor lasers operating CW, having a single active region and oscillating primarily in one dominant mode. It is shown that the intensity fluctuations in the nonlasing modes occur with characteristic times of a few nanoseconds and have exponential probability distributions ...

Pressure tuned single longitudinal mode dye laser

Optics Communications, 1987
Abstract The design and construction of a pressure tuned single longitudinal mode (SLM) dye oscillator is described. The oscillator had a pressure tuned range of ⩾ 3.75 cm −1 and a time average linewidth of 0.019 cm -1 . The output of the oscillator could be increased by four orders of magnitude in an amplifier chain which incorporated a phase ...

Single longitudinal-mode optical phonon scattering in Ga0.47In0.53As

Applied Physics Letters, 1983
We show that only one of the four Raman active modes in Ga0.47In0.53As shows the required symmetry behavior for longitudinal optical (LO) phonons. An additional mode previously supposed to be LO shows mixed-mode behavior and may be disorder activated.

Single-longitudinal-mode multiwavelength fiber ring laser

IEEE Photonics Technology Letters, 2004
A single-longitudinal-mode multiwavelength fiber ring laser is proposed and demonstrated. The single-longitudinal-mode operation is realized using a fiber loop mirror with a saturable absorber. The fiber loop mirror acts as a passive self-tracking narrow multiband optical filter.
