L-Band Erbium Fiber Laser with Tunable and Narrow Sub-kHz Linewidth Output

Applied Sciences, 2023
In this paper, a wavelength-selectable erbium-doped fiber (EDF) laser in L-band bandwidth with a simple structure and low cost is described. To obtain stable single-longitudinal-mode (SLM) and narrow laser linewidth, the 2 m unpumped EDF-based saturable ...

800 nm narrow linewidth tunable hybrid laser based on a dual microring external cavity [PDF]

, 2023
We present a novel hybrid 800 nm laser with a wide tuning range, high optical power and ultra-narrow linewidth with >kHz tuning speeds and a small footprint. Tunable, narrow linewidth hybrid lasers around 800nm serve as an attractive choice for e.g. OCT,

Operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser [PDF]

, 2006
We report the operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser. The laser delivers 1 W at 855 nm and is pumped with a cost-effective fiber-coupled laser diode emitting at 806 nm.

Narrow-linewidth fiber laser operating at 155 μm [PDF]

Optics Letters, 1987
We report the fabrication and operation of an Er(3+)-doped silica single-mode fiber laser operating at 1.55 microm and using a distributed fiber grating to provide feedback. The output bandwidth was measured as 0.04 nm, significantly narrower than the conventional cavity design. The laser had a threshold of 13 mW and a slope efficiency of 5%.

Tunable Narrow-Linewidth Ring Laser Based on the Polarization Conversion in a Tapered Fiber-Coupled Whispering Gallery Mode Resonator

Crystals, 2021
Based on the polarization conversion in a tapered fiber-coupled whispering gallery mode (WGM) system, a simple-structured narrow linewidth band-pass filter was fabricated and a narrow linewidth ring laser was demonstrated. With a fiber Bragg grating (FBG)
