  • A neodymium phosphate glass regenerative amplifier is used for both pulse energy amplification and spectral broadening. After compression by a grating pair, 0.55 ps pulses of 11 ..mu..J energy are generated at a 370 Hz repetition rate.
  • The transfer of energy between electrons and an electromagnetic field via nonlinear radiation pressure effects is discussed. It is shown that a net transfer of energy from electrons to the interacting field is possible if the field intensity changes with time while its relative spatial distribution is maintained. Ignoring the space-charge effects an expression is derived for the gain of an amplifying system, based on this concept.
  • The authors demonstrate the amplification of femtosecond dye laser pulses up to the 3.5 mJ level in an alexandrite regenerative amplifier. An expansion/compression system using diffraction gratings allows chirped pulse amplification techniques to be used to produce peak powers upwards of 1 GW. Limitations in the chirped pulse amplification of ultrashort pulses due to intracavity dispersive elements are discussed.
  • We demonstrate a regenerative amplifier incorporating alexandrite as the gain medium that is pumped by an alexandrite laser. Temperature-altered gain permitted the 728-nm alexandrite pump laser, operating at room temperature, to pump a 780{endash}800-nm alexandrite laser that was maintained at elevated temperatures. 200-fs pulses from a Ti:sapphire oscillator were amplified to the millijoule level. This system also amplified femtosecond pulses from a frequency-doubled Er-doped fiber laser. {copyright} {ital 1996 Optical Society of America.}
  • Regenerative pulse shaping is used to alleviate gain narrowing during ultrashort-pulse amplification. Amplification bandwidths of {approximately}100 nm, or nearly three times wider than the traditional gain-narrowing limit, are produced with a modified Ti:sapphire regenerative amplifier. This novel regenerative amplifier has been used to amplify pulses to the 5-mJ level with a bandwidth sufficient to support {approximately}10-fs pulses. {copyright} {ital 1996 Optical Society of America.}
