Thermal management in quasi-waveguide amplifiers based on Herriott cells [PDF]

EPJ Web of Conferences
We present a new geometry for laser amplifiers with bulk laser gain media based on the quasi-waveguide property of Herriott cells. A proof-of-principle experiment and numerical simulations of the heat equation indicate a potential advantage in terms of ...

Development of a two arm, high energy, high power laser for plasma research in India

EPJ Web of Conferences, 2013
We report here work done towards development of a two arm, high energy, high power Nd:phosphate glass laser system. One arm of the laser is proposed to be operated in a long pulse (∼1.5ns pulse duration) with an energy of ∼400 J.

Optimization and Demonstration of Direct LD Pumped High-Power Fiber Lasers to Balance SRS and TMI Effects

Photonics, 2023
Up to now, transverse mode instability (TMI) and stimulated Raman scattering (SRS) have become the main factors limiting the power scaling of conventional ytterbium-doped fiber laser. Many technologies are proposed to suppress the SRS or TMI individually,

Wavelength conversion for WDM communication systems using four-wavemixing in semiconductor optical amplifiers [PDF]

, 1997
Four-wave mixing (FWM) in semiconductor optical amplifiers is an attractive mechanism for wavelength conversion in wavelength-division multiplexed (WDM) systems since it provides modulation format and bit rate transparency over wide tuning ranges.

Ultrafast ytterbium-doped bulk lasers and laser amplifiers [PDF]

Applied Physics B: Lasers and Optics, 1999
We review recent achievements with ultrafast bulk lasers and amplifiers based on Yb:YAG and Yb:glass. Special attention is paid to those aspects of the quasi-three-level nature of these gain media that are important for short-pulse generation. The potential of Yb-doped media for efficient short-pulse generation and amplification is compared to their Nd-
