What the Future Prospects May Bring in Femtosecond Laser Applications

The femtosecond laser is an infrared laser (wavelength: 1,053 nm) with an ultrashort pulse duration (10-15 s). The early femtosecond laser systems operated with a low repetition rate (15 kHz) and thus required higher energy to operate. The new devices have an increased repetition rate (as high as 150 kHz), which leads to the utilization...
