A 440-fsec, 0.1-pJ pulse from a dye laser is injected into a high-repetition-rate Ti:Al2O3 laser pumped by a copper-vapor laser to study the amplification and pulse broadening of femtosecond pulses in Ti: Al2O3. Gains of 2 × 107 are achieved with output pulse durations of 1.1 psec. After recompression with a grating pair to compensate dispersion broadening, pulses as short as 275 fsec are obtained.
