We have developed a compact Ti:sapphire laser system operating at variable repetition rates up to 40 kHz. Pulses of 13.2 fs from a cavity-dumped oscillator were amplified further by a seven-pass confocal amplifier, and after compression 23.8-fs pulses with a maximum pulse energy of 1.25 µJ at 10 kHz and more than 100 nJ at 25 kHz were generated. A new prismless cavity-dumping oscillator configuration was designed with the use of negatively chirped mirrors for dispersion compensation. Application of the developed laser system for nonlinear optical spectroscopy in condensed phase was demonstrated.
