WebThe mobile femtosecond-terawatt laser system, has been constructed to study these applications, and pulse shaping was expected to benefit in terms of phase correction of the laser pulse after long-range (up to a few tens of km) propagations in air, as well as identifying bioagents that have identical linear fluorescence spectrum [Citation 249–251]. WebUltrafast lasers. Ultrafast lasers are generally defined as lasers that produce pulses in the range of 5 fs to 100 ps (1 femtosecond = 10 −15 seconds). If a laser is able to oscillate in many longitudinal modes, such short pulses can be produced with the so-called mode-locking technique.
