A neodymium glass laser system capable of generating high-energy, ultrashort pulses at a convenient repetition rate is described. The effect of nonlinear frequency pulling on active mode locking is discussed. By minimizing the nonlinear frequency pulling, the authors can routinely generate stable --10 ps pulses at 100 MHz repetition rate from the actively mode-locked oscillator. The regenerative amplifier increases the oscillator pulse energy to over 30{mu}J at a 370Hz repetition rate. Using intracavity self-phase modulation, the regenerative amplifier also broadens the pulse bandwidth to --35A. By subsequent pulse compression maintaining high energy, they can produce 0.55 ps pu8lses with >10{mu}J. An optical fiber pulse compressor further shortens the pulses to 30 fs (30nJ).
