Laser system using ultra-short laser pulses

Abstract

A laser system using ultrashort laser pulses is provided. In another aspect of the present invention, the system includes a laser, pulse shaper and detection device. A further aspect of the present invention employs a femtosecond laser and binary pulse shaping (BPS). Still another aspect of the present invention uses a laser beam pulse, a pulse shaper and a SHG crystal.

Background technique [0003] The present application relates generally to a laser system, and more particularly to a laser system using ultrashort laser pulses and a pulse shaper. [0004] Commercially practical femtosecond lasers are not yet available. For example, lasers capable of producing laser pulse durations of 10 femtoseconds or less are conventionally very expensive, require unrealistically high power consumption (e.g., extensive cooling), and rely on laser dyes that are replenished monthly , thus leading to commercia...
