Thus, under the combined filtering effects, the pulses with different pulse width could be obtained by carefully adjusting the PCs in the laser. Here, the laser can emit both femtosecond pulse and picosecond pulse. Once the bandwidth of the combined filters is wide enough by appropriately rotating the PCs, the femtosecond pulse can be generated.

A Guide to Femtosecond Lasers - IMRA America, Inc.

A femtosecond laser is a device that emits optical pulses of infrared (IR) laser light with durations on the femtosecond scale. Electromagnetic pulses with a duration of picoseconds or less are classified as ultrashort pulses, which typically exhibit peak powers on the order of megawatts (MW) or more and correspondingly high pulse repetition frequencies.
