Producing 4mJ, 25 fs Pulses from a kHz Laser Using a Single Stage Multipass Amplifier

Reference Number: 03-09

Inventors: Bing Shan, Chun Wang and Zenghu Chang

Description:

This invention provides for the production of 4 mJ, 25 fs pulses from a laser that uses a single multipass amplifier operating as a 1 kHz repetition rate. The peak power capability is 1.6x1011 Watts.

Applications

This invention provides the highest peak power developed from a kHz laser using a one-stage amplifier. This single stage amplifier configuration has high power and efficiency at a much lower cost than is the case for similar outputs from the current two-stage configurations. Another feature of this invention is that a clean laser spatial profile results.

Advantages

Ultrafast, high intensity lasers are becoming important tools for both research and industry. Selected examples are high field atomic physics, coherent x-ray generation, and industrial applications, such as micro-machining.
