Single Longitudinal Mode Green Diode Laser
Frontiers in Optics 2016, 2016We observed that a green diode laser shows single longitudinal mode output at low operation current, and its frequency can be tuned by adjusting the operation temperature and operational current. The behavior of laser modes with operational current was also investaigated.

Widely tunable single-longitudinal-mode pulsed dye laser
Optics Letters, 1989We have developed a simple cavity-length-stabilization method appropriate for single-longitudinal-mode pulsed lasers that use grazing-incidence gratings. Our technique relies on the detection of aminute (

Single-longitudinal-mode, tunable, pulsed Ti:sapphire laser oscillator
Optics Letters, 1989A 2.0-mJ/pulse, 2-nsec, single-longitudinal-mode Ti:sapphire laser oscillator has been demonstrated in a compact grazing-incidence cavity configuration similar to a Littman arrangement. The oscillator's output beam quality is TEM(00), making it attractive for doubling and mixing applications.

Tunable single-longitudinal-mode fiber optical parametric oscillator
Optics Letters, 2010A tunable single-longitudinal-mode (SLM) fiber optical parametric oscillator (FOPO) is proposed and demonstrated experimentally. A sub-ring cavity with a short cavity length is used to suppress the longitudinal modes and broaden the longitudinal mode spacing.

Tunable, Single-Longitudinal Mode 2 μm VECSEL
Frontiers in Optics + Laser Science APS/DLS, 2019A 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.

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 ...

Single longitudinal mode operation of diode lasers
Applied Physics Letters, 1977We report single longitudinal mode operation of conventional double-heterostructure GaAs/GaAlAs diode lasers achieved by heavy p-type doping of the active region. At 77 °K a broad-area device pumped with a rectangular current pulse exhibited single longitudinal mode operation up to 2.8 times threshold, which was the limit of the pulser.

Resonantly pumped single-longitudinal-mode Ho:YAG laser
Applied Physics B, 2016We 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.

Spectrum of single bunch longitudinal dipole modes
Physical Review E, 1998A mode of coherent longitudinal dipole motion of the beam in the National Synchrotron Light Source (NSLS) vacuum ultraviolet (vuv) ring with small frequency is observed by Biscardi {ital et al.} [Rev. Sci. Instrum. {bold 66}, 1856 (1995)]. We point out in this paper that the coherent motion observed is, although a solution to the well-known secular ...
