Abstract
A simple and low-cost apparatus amplifies short optical pulses (e.g., in the femtosecond domain) to high pulse energies using energy stored in an enhancement cavity. The enhancement cavity is first filled with pump light from a pump laser; and a signal laser then directs a signal pulse into the cavity, where the signal pulse and pump laser both pass through a non-linear medium for parametric amplification of the signal pulse, wherein energy from the aggregated pump light is transferred to the signal pulse, which then exits the enhancement cavity.
