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.

Single-longitudinal-mode laser as a discrete dynamical system

Journal of the Optical Society of America B, 1985
A solid-state laser running on a single longitudinal mode can show chaotic time behavior if several transverse modes are excited. The temporal development of the laser is approximated by a Kirchhoff integral together with a rate equation for the inversion.

Resonantly pumped single-longitudinal-mode Ho:YAG laser

Applied Physics B, 2016
We demonstrated a 1.9-μm-pumped high-efficiency single-longitudinal-mode Ho:YAG laser with intra-cavity etalons for the first time. By inserting the F–P etalons into the laser cavity, single-longitudinal-mode Ho:YAG lasing was achieved at a wavelength of 2081.2 nm.

Single longitudinal mode operation of the electron-beam-pumped semiconductor laser

IEEE Journal of Quantum Electronics, 1986
The influence of the external and internal resonator parameters on the laser emission spectral and spatial characteristics has been investigated. Single longitudinal mode operation of the electron-beam-pumped visible semiconductor laser with an external resonator has been observed.

Power dropout statistics of nearly single-longitudinal-mode semiconductor lasers

Conference on Lasers and Electro-Optics, 1984
Mode partition noise is unavoidable with semiconductor lasers, even when the laser is oscillating in a nearly single longitudinal mode.1-4 This noise shows up in the form of power dropouts in the main mode, and power increases in the side modes. Such power dropouts were first observed by Linke et al.5 Main-mode power dropouts can affect the performance
