LASERFOCUS: Autofocus for ultrafast lasers

An autofocus system for femto/pico second pulsed lasers based on the coherence between incident and reflected light from the sample.

Benefits:

• Automatic focusing : no human intervention (delay line embedded)
• Accurate : the sample is in the exact focal point, even for rugged surfaces
• Adaptable : no need to change anything when working on new samples
• Fast : the tuning is made in few seconds
• Contactless : adjustments are made remotely with light feedback in a meter range
• Polyvalent : it works for a large range of wavelength
