Femtosecond-laser Process
Femtosecond-laser Process
update :
– Features –
– Ultra-short pulse laser process:
1 femtosecond is one petaseconds.
(The light can travel only 0.3 μm in one femtosecond.)
– Minimum thermal effect to materials
– High precision work:
Working accuracy is submicrons to microns.
