Pulse amplification in a Cr ⁴⁺ :forsterite single longitudinal mode (SLM) multi-pass amplifier

Laser Physics, 2019
Abstract An efficient multi-pass Cr:forsterite master oscillator-power amplifier laser system operating in the single-longitudinal mode was demonstrated and characterized. A significant increase in energy was obtained in a six-pass amplifier configuration giving a maximum value of up to 10.8 mJ, with a good beam ...

Tunable Yb-doped fiber laser with single longitudinal mode (SLM) operation based on subring cavities

2015 International Symposium on Next-Generation Electronics (ISNE), 2015
1064 nm band Ytterbium doped fiber (YDF) laser is proposed and investigated. Using 70 cm YDF and FBG parameter optimization reflectivity and pumping scheme, a high slope efficiency of 50% and low threshold power are obtained. The power variation is less than 0.1 dB in 13 nm tuning span. Using the Vernier effect, near single frequency lasing is realized

Use of fiber Bragg grating (FBG) for stable and tunable erbium-doped fiber ring laser with single-longitudinal-mode (SLM) output

Laser Physics, 2015
In this demonstration, we propose and investigate a stable C-band erbium-doped fiber (EDF) laser with compound-ring cavity. To achieve wavelength tunability with single-longitudinal-mode (SML) output, the sub-ring scheme and fiber Bragg grating (FBG) are used inside the ring cavity.

Single-Longitudinal-Mode (SLM) Generation at Power Diode Lasers by Using a Diffracto-Optical External Cavity

1994
Environmental research at the atmosphere contains a lot of methods investigating the chemical nature of air pollutions and their distribution in the air. Laser spectroscopic methods and Lidar among these are able to solve some of that tasks. Laser analytical investigations make necessary tunable laser sources.
