Partition fluctuations in nearly single-longitudinal-mode lasers
Journal of Lightwave Technology, 1984A 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, 1987Abstract 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 ...

III Single-Longitudinal-Mode Semiconductor Lasers
1988Publisher 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

Single longitudinal-mode optical phonon scattering in Ga0.47In0.53As
Applied Physics Letters, 1983We 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.

The study of 33 mode single crystal longitudinal transducer
2015 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA), 2015There are many advantages of broadband transducers, such as reducing of signal distortion, widening the security about information transmission, reducing the ratio of false codes. The use of eight 33 mode single crystal pieces, a thin light beryllium alloy head mass and a thick heavy tungsten alloy tail mass can expand the bandwidth of the middle ...
