Regenerative Nd:glass amplifier seeded with a Nd:fiber laser [PDF]

Optics Letters, 1992
Wavelength tuning and broad-bandwidth operation of a passively mode-locked Nd:fiber laser is demonstrated at 1060 microm. The oscillator pulses are used to seed a bulk regenerative Nd:glass amplifier, and 300-fs transformlimited pulses with an energy of 10 microJ are obtained after 31 round trips at a repetition rate of 500 Hz.

Simulation of a regenerative MW FEL amplifier [PDF]

, 1997
Both oscillator and regenerative amplifier configurations are being studied to optimize the design of a MW-class FEL. The regenerative amplifier uses a longer undulator and relies on higher extraction efficiency to achieve high average power, whereas the

Indirectly LED-pumped Nd:glass regenerative amplifier

Optics Express
We demonstrate the first LED-pumped Nd:glass regenerative amplifier. It delivers 2 ns pulses at 1053 nm with an energy of 3.8 mJ at a repetition rate of 2 Hz. This performance is achieved using a Ce:LuAG luminescent concentrator producing 3.4 kW of optical peak power in the yellow spectral range and pumped by 3200 blue LEDs.
