Structure of a femtosecond laser

When ultrashort pulse lasers are laser sources referred to, the pulsed laser light with pulse durations in the range of picoseconds and femtosecond emit.

definition

The picosecond lasers and the femtosecond lasers fall under ultrashort pulse lasers . As a rule, these are mode-locked lasers. Attosecond lasers (1,000 attoseconds = 1 femtosecond) have already been developed in research. According to current usage, these are also considered to be ultra-short pulse lasers.

The first ultrashort pulse lasers were dye lasers . A major development for ultrashort pulse laser technology was the discovery of titanium in 1982 : sapphire laser .
