An Alexandrite Regenerative Amplifier

Advanced Solid State Lasers, 1987
In order to obtain very stable frequency output or very short pulses from a laser, cw pumping of the laser has been required. The ability to amplify frequency stable output, short pulses, or diode laser pulses to pulse energies available from pulsed solid-state lasers is highly desirable.

42  W femtosecond Yb:Lu_2O_3 regenerative amplifier

Optics Letters, 2016
We report on a femtosecond high-power regenerative amplifier based on Yb:Lu2O3. Exploiting the excellent thermo-mechanical properties of this material, we were able to achieve up to 64.5 W in continuous-wave regime, limited only by the available pump power.

High-power regenerative Nc:phosphate glass amplifier

Applied Optics, 1985
A compact high-power regenerative Nd:phosphate glass amplifier is described which incorporates spatial filtering and full image relay techniques. Output energies up to 1.2 J at a pulse duration of 140 ± 10 psec (FWHM) and 3 J at 900 ± 70 psec (FWHM) are achieved in a smooth nearly flattop beam intensity profile.

Flashlamp-Pumped Cr:liSAF Regenerative Amplifier

Advanced Solid State Lasers, 1992
We report the first operation of a flashlamp-pumped LiSrAlF6:Cr3+ regenerative amplifier for chirped 100fs pulses leading to a single chirped pulse energy of 2.5mJ.

CO2 Regenerative Ring Power Amplifiers

Journal of Applied Physics, 1971
An unidirectional regenerative ring CO2 power amplifier is described. Both below threshold (unconditionally stable) and above threshold (conditionally stable) operation are discussed. Analytic expressions for a homogeneously broadened medium are presented for the power extracted from the active medium, the circulating power, and the total output power ...

Regenerative Yb:KLuW thin disk amplifier

CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009
Ytterbium doped monoclinic double tungstates, like Yb:KYW or Yb:KGW, are attractive gain media for ultrafast laser and amplifier systems, respectively. This is owing to the high absorption and emission cross-section peaks and the broad emission bandwidth.

Diode-pumped Nd:YLF regenerative amplifier

SPIE Proceedings, 2002
A diode pumped Nd:YLF regenerative amplifier is developed, which works at wavelength of 1053nm and repetition rates of 1Hz. It can produce laser pulses of 2mJ energy, 4ns width in the base transverse mode TEM00. Total gain of 1x107 is reached, and pulse-to-pulse energy fluctuation doesn't exceed ±4.7% Experimental setup and detailed results are ...

Femtosecond Yb:YGAG ceramic regenerative amplifier

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
Ytterbium-doped gain media are excellent materials for high power ultrashort pulse lasers. Especially Yb:YAG is very well established in picosecond lasers systems with kW power level due to its excellent optomechanical properties. However, limiting factor for amplification of high energy sub-picosecond and femtosecond pulses in Yb:YAG laser amplifiers ...

10 kHz 40 W Ti:sapphire regenerative ring amplifier

Optics Letters, 2006
A cryogenically cooled Ti:sapphire regenerative ring amplifier was developed as a laser for generating a laser-produced plasma light source. With a 10 kHz 180 W pump laser, the amplifier output is 40 W before compression and 26 W after compression. We believe it to be the current highest average-power output from a single stage Ti:sapphire amplifier ...

Transistor Pulse Regenerative Amplifiers

Bell System Technical Journal, 1956
A pulse regenerative amplifier is a bistate circuit which introduces gain and pulse reshaping in a pulse transmission or digital data processing system. Frequently it is used also to retime the pulses which constitute the flow of information in such systems.
