Query: Overcoming Bifurcation Instability in High-Repetition-Rate Ho:YLF
  Regenerative Amplifiers   We demonstrate a Ho:YLF regenerative amplifier (RA) overcoming bifurcation
instability and consequently achieving high extraction energies of 6.9 mJ at a
repetition rate of 1 kHz with pulse-to-pulse fluctuations of 1.1%. Measurements
of the output pulse energy, corroborated by numerical simulations, identify an
operation point that allows high-energy pulse extraction at a minimum noise
level. Complete suppression of the onset of bifurcation was achieved by gain
saturation after each pumping cycle in the Ho:YLF crystal via lowering the
repetition rate and cooling the crystal. Even for moderate cooling, a
significant temperature dependence of the Ho:YLF RA performance was observed.
