Flexible and Rapidly Configurable Femtosecond Pulse Generation in the Mid-IR



S M. Foreman, D J. Jones, Jun Ye


We demonstrate a new experimental approach for flexible femtosecond pulse generation in the mid-IR using difference-frequency-generation from two tightly synchronized Ti: sapphire lasers. The resultant mid-IR pulse train can be easily tuned, with an adjustable repetition frequency up to 100 MHz and a pulse energy of 1.5 x 10-13 J. Rapid switching of the MIR wavelength and programmable amplitude modulation are achieved via precision setting of time delay between two original pulses.
