Embodiment Construction

[0035] The following description of the preferred embodiment is by way of illustration only and is not intended to limit the invention and its application or uses.

[0036] The present invention provides methods and apparatus for laser systems using ultrashort pulses. Pulse shaping mainly involves the control of amplitude, phase, frequency and / or separation of alternating pulses. The goal of complex pulse shaping is to control one or more of the above parameters in a programmable manner so that the user has complete control. In other words, complex pulse shaping allows complex ultrafast optical waveforms to be generated according to user specifications.

[0037] Coherent control is the ability to control kinetics at various stages of a process as it develops under the action of a coherent source. The many frequencies that make up ultrafast pulses can simultaneously excite many coherent transitions to excited states, and the ability to manipulate them using shaped pulses lead...

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.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of U.S. Patent Application No. 10 / 791,377, filed March 2, 2004, which is a continuation-in-part of U.S. Patent Application No. 10 / 265,211, filed October 4, 2002 A continuation-in-part of PCT / US02 / 02548 filed on the 8th and claiming priority to US Provisional Application No. 60 / 265,133 filed on January 30, 2001, which is incorporated herein by reference. 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...
