Here, we present a novel technique for time resolved experiments without any moveable external delay line. Optical Sampling by Cavity Tuning (OSCAT) method is based on a femtosecond laser with a tunable repetition rate and a passive delay line. The time delay between the pump and probe pulses is determined by the repetition rate of the femtosecond laser.
