Method and radiation source for generating pulsed coherent radiation


Sensors, Devices and Components

Ref.-No.: 1302-3482-WT

The present invention relates to a method of generating pulsed coherent radiation in the UV and XUV wavelength ranges. Furthermore, the present invention relates to a radiation source for generating pulsed coherent radiation based on a high harmonic generation (HHG).

Technology

A method of generating pulsed coherent radiation, comprises the step of generating high harmonic pulses by an interaction of laser light pulses with a non-linear medium contained in a resonant cavity, wherein the non-linear medium is arranged in an environment of reduced pressure. Furthermore, a radiation source of generating pulsed coherent radiation is described, comprising a laser pulse source for generating laser light pulses, a resonant cavity including a non-linear medium for generating high harmonic pulses by an interaction of the laser light pulses with the non-linear medium, wherein the non-linear medium is arranged in an environment of reduced pressure.
