Widely Wavelength-Tunable High Power Single-Longitudinal-Mode Fiber Laser in Mid-Infrared Waveband
Applied Sciences, 2021 We demonstrate a mid-infrared (MIR) wavelength-tunable high-power single-longitudinal-mode (SLM) fiber laser using a compound cavity structure. The compound cavity consists of an Er-doped ZBLAN fiber perpendicularly cleaved at two-ends and an external ...

Continuous-wave single-longitudinal-mode fiber-optical parametric oscillator with reduced pump threshold [PDF]
, 2009 A single-longitudinal-mode (SLM) fiber-optical parametric oscillator (FOPO) is proposed and demonstrated experimentally. The FOPO operates fundamentally by resonating the nondegenerate signal and idler in two separate optical cavities independently ...

Wavelength-tunable single longitudinal mode fiber optical parametric oscillator
Optics Express, 2017 We demonstrate a ring cavity single longitudinal mode fiber optical parametric oscillator using a passive sub-ring cavity and an unpumped erbium doped fiber configured with an external fiber mirror for single mode selection. The unpumped erbium doped fiber uses its saturable absorption characteristic to generate a self-induced narrowband filter when ...

Fiber laser development for LISA
, 2010 We have developed a linearly-polarized Ytterbium-doped fiber ring laser with single longitudinal-mode output at 1064nm for LISA and other space applications. Single longitudinal-mode selection was achieved by using a fiber Bragg grating (FBG) and a fiber
