A Very Brief Guide to Femtosecond Lasers

Lasers emit light either continuously or in a train of pulses. Under the heading of ultrafast lasers falls a certain group of lasers that produce picosecond, femtosecond or even nanosecond pulse durations at different repetition frequencies. Within this group, femtosecond lasers emit optical pulses with a pulse duration in the domain of femtoseconds (1 fs […]
