Cr:LiSrAlF_6 regenerative amplifier

Optics Letters, 1992
The design and performance of a flash-lamp-pumped regenerative amplifier that utilizes the new laser material Cr:LiSrAlF(6) is described. The device can be used for tunable and/or short-pulse amplification to the 10-mJ level at a repetition rate of 10 Hz. Using chirped-pulse amplification, we have achieved 8-mJ pulses with a duration of 150 fs.

Kilohertz Cr:forsterite regenerative amplifier

Optics Letters, 1998
We report on a tunable regenerative amplifier that is operational in the near-infrared spectral region from 1230 to 1280 nm based on the vibronic laser material Cr:forsterite. Utilizing the technique of chirped-pulse amplification, we generated pulses as short as 150 fs at 1255 nm at a repetition rate of 1 kHz. Pulse amplification of more than 5 x 10(5)

Diode-pumped Nd:YLF regenerative amplifier

Optics Letters, 1992
A diode-pumped Nd:YLF regenerative amplifier operating at 1047 nm produces 88-microJ, 11-ps pulses at a 1-kHz repetition frequency. Switching of the 250-MHz seed pulses with a Pockels cell in the half-wave configuration is achieved with a contrast ratio of 20:1.

Wavelength tunable alexandrite regenerative amplifier

Applied Optics, 1988
We describe a wavelength tunable alexandrite regenerative amplifier which is used to amplify nanosecond slices from a single-frequency cw dye laser or 50-ps pulses emitted by a diode laser to energies in the 10-mJ range. The amplified 5-ns slices generated by the cw-pumped line narrowed dye laser are Fourier transform limited.

Amplified spontaneous emission in a Ti:sapphire regenerative amplifier

Applied Optics, 2003
Amplified spontaneous emission power and contrast ratio in a linear miltipass Ti:sapphire regenerative amplifier with a wavelength centered at 1054 nm are calculated and measured. It is shown that the passive losses of a seed pulse and the losses in coupling to the regenerative amplifier cavity mode degrade the intensity contrast ratio to 10(-6)-10(-7).

Femtosecond Yb:CALGO regenerative amplifier

Advanced Solid-State Lasers Congress, 2013
This study reports the first diode-pumped Yb:CALGO regenerative amplifier. It generates pulses at 1050 nm with up-to-240-μJ energy (before compression), with pulse duration near 350-450 fs and with a 5 nm spectral bandwidth.

ND : YAG regenerative amplifier

Journal of Applied Physics, 1980
The Nd : YAG regenerative amplifier produces short-duration, optical pulses with the stability and pulse width range characteristic of actively mode-locked lasers and the pulse energy characteristic of passively mode-locked lasers. Other important properties, including large amplification and optical pulse storage, have also been achieved.

High-power regenerative amplifier

SPIE Proceedings, 2000
We have been investigating the possibility of ultimate down sizing of the CPA system by improving over all efficiency to convert the green pump energy to the Ti:sapphire wavelength by optimizing the regenerative amplifier. A regenerative amplifier with high gain to achieve small signal and saturated amplification was constructed.

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-
