Micromachining with a High Repetition Rate Femtosecond Fiber Laser

Industrial micromachining applications with ultrashort pulse lasers are often difficult to make practical due to the lack of robustness of the laser and the slow processing speed resulting from the low repetition rate. In the past, amplified, femtosecond lasers produced high pulse energies, but at a slow pulse repetition rate of around a kHz. The high repetition rate oscillators did not have enough pulse energy for micromachining of most industrial materials.
