Regenerative Ruby Laser Amplifiers

Journal of the Optical Society of America, 1966
An ideal laser amplifier was previously treated as a three-medium transmission system. It was predicted that for a given length, the gain would rise with negative attenuation (population inversion), reach a maximum, decrease rapidly at first, and then gradually approach zero asymptotically.The theory has been tested experimentally, using ruby at liquid-

Nd:YLF mode-locked oscillator and regenerative amplifier

Optics Letters, 1987
Pulses of 37-psec duration are generated by a cw actively mode-locked Nd:YLF oscillator and subsequently amplified to 2.5 mJ in a cw-pumped Nd:YLF regenerative amplifier operating at a repetition rate of 500 Hz. In comparison, the same system refitted with Nd:YAG gain media produces longer pulses (~80 psec) with lower energy (1 mJ).

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.

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.

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.

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.

Regenerative amplifiers with one phase-conjugate mirror

Optics Letters, 1984
We study the operating characteristics of a cavity with a gain medium inside and one phase-conjugate mirror as a regenerative amplifier. We show that, for this cavity to work efficiently, the phase-conjugate mirror must have a reflectivity in a certain range determined by the reflectivity of the ordinary mirror.

Analysis of a Regenerative Amplifier with Distributed Amplification

Proceedings of the IRE, 1956
It is shown that regenerative circuits of the discontinuous-output type such as the monostable multivibrator do not have their high speed performance improved by the use of distributed amplification in the amplifier portion.
