Yb:GdCOB regenerative amplifier

Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Technical Digest (IEEE Cat. No.01CH37170), 2001
Summary form only given. In this summary, we present the first Yb:GdCOB regenerative chirped pulse amplification system to produce 12-mJ, and 350-fs pulses. We have extracted reasonable amount of energy from Yb:GdCOB. If we employ a diode-pumping scheme, we could obtain hundreds, of milli-joule pulses with high repetition rate.

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.

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.

Regenerative amplifier with pulse-on-demand

SPIE Proceedings, 2012
A picosecond regenerative amplifier with pulse on demand operation is demonstrated. The pulse energy is held constant for arbitrary pulse separation by employing an intracavity loss modulator. The loss modulator is controlled by a digital signal processor monitoring the gain of the laser material in real time. The gain is estimated from a measurement

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.

Broadband Spectral Shaping in a Ti:Sapphire Regenerative Amplifier

Optics and Laser Technology, 2003
Abstract A birefringent crystal quartz plate of known thickness has been used as a spectral filter for spectral shaping in a Ti:sapphire regenerative amplifier. The spectral profile of the amplified pulse ejected from the regenerative amplifier was observed while adjusting the birefringent crystal plate in the cavity.

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.

Optical Parametric Chirped-Pulse Amplifier as an Alternative to Ti:Sapphire Regenerative Amplifiers

Applied Optics, 2002
We demonstrated a high-pulse energy, femtosecond-pulse source based on optical parametric chirped-pulse amplification. We successfully amplified 1-microm broadband oscillator pulses to 31 mJ and recompressed them to 310-fs pulse duration, at a 10-Hz repetition rate.

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.
