Single longitudinal mode fiber ring laser [PDF]
Optics & Laser Technology, 2018 In this work, a dual-wavelength fiber ring laser working on the SLM regime is proposed and experimentally verified. A proof-of-concept device has been tested employing high precision small-sized SLM fiber lasers to complement the feedback produced by a passive FBG.

Single Longitudinal Mode and Widely Tunable Er:Y2O3 Ceramic Laser at ∼ 2.7 μm
IEEE Photonics Journal, 2023 We report on single-longitudinal-mode and tunable operation of an Er:Y2O3 ceramic laser at ∼2.7 μm using intracavity Fabry-Perot etalons combined with a birefringent filter. The laser is pumped with a high brightness, narrow linewidth diode

A Resonantly Pumped Single-Longitudinal Mode Ho:Sc2SiO5 Laser with Two Fabry–Perot Etalons
Applied Sciences, 2017 We present a single-longitudinal-mode Ho:Sc2SiO5 (Ho:SSO) laser pumped by a Tm:YAP laser for the first time. Two intra-cavity Fabry–Perot etalons were used to realize the single-longitudinal mode of operation.

A groove GaInAsP laser on semi-insulating InP using a laterally diffused junction [PDF]
, 1982 Low threshold current GaInAsP/InP groove lasers have been fabricated on semi-insulating InP substrates. Three n-type layers are grown with a single liquid phase epitaxial (LPE) growth process, and the p-n junction is formed by a lateral Zn diffusion. The
