Ultrafast lasers

Our ultrafast laser components are used for pulse stretching and dispersion compensation in chirped pulse amplification (CPA) designs of ultrafast lasers that generate femtosecond or picosecond pulses. Such ultrafast lasers are often used in applications that require extremely precise cutting, such as ophthalmology, cold ablation and transparent material processing.
