One could take advantage of the temporal deformation to compress the pulse into a few energetic cycle pulses [12]. Laser pulse picker UP2 in set-up with timing generator pMaster 4.2 allows to select single femtosecond pulses from the train at up to 2 Mhz rate. Mode-locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 −12 s) or femtoseconds (10 −15 s). A laser operated in this way is sometimes referred to as a femtosecond laser, for example in modern refractive surgery.

Femtosecond laser pulse

Thermal load generates a diverging lens due to thermal expansion (hence negative n 2 ) and since both methanol and carbon disulfide have negligible absorption at 800 nm, their n 2 values are similar. The ability of femtosecond lasers to efficiently fabricate complex structures and devices for a wide variety of applications has been extensively studied during the last decade. State-of-the-art laser processing techniques with ultrashort light pulses can be used to structure materials with a sub-micrometer resolution.

Read on to learn  Jan 22, 2019 Over the last five years, material processing with femtosecond pulses in the range of 300 to 900 fs has gained in popularity.
