Femtosecond Laser

The Key Features
1

The femtosecond micromachining system is mainly composed of a femtosecond laser and a high-precision platform. It utilizes the ultrashort laser pulse properties to achieve an unprecedented degree of control in sculpting the desired microstructures internal to the materials without collateral damage to the surroundings. Using femtosecond rather than picosecond or nanosecond light pulses, laser energy is deposited into small volumes by multiphoton nonlinear optical absorption followed by avalanche ionization.
