Problems solved by technology

Nanosecond-level pulse time is an urgently needed light source technology feature for detecting many physical and chemical reactions or illuminating objects with high-speed motion. Although nanosecond lasers can meet the requirements in terms of pulse time and brightness, their good monochromatic Sexuality has become an obvious shortcoming when used as a detection and illumination source

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0040] Such as figure 1 As shown, it is a high-brightness pulsed white light source excitation system provided by the present invention. On the optical path of the laser pulse 1 output by the nanosecond pulse laser, the beam expander lens group 2, the focusing lens 3 and the gas chamber 4 (high-pressure xenon lamp bulb) are fixed in sequence. , and ensure that the laser focus is located in the gas chamber 4 . The laser pulse 1 is focused into the gas chamber 4 by the focusing lens 3, and the light emitted by the generated plasma flame is collected by the collection lens group 5 to obtain a high-brightness pulsed white light source, and the central axis of the collection lens group 5 is perpendicular to the direction of the laser light path. And the laser focus is located at a focal point of the len...

Abstract

The invention discloses a high-brightness pulse white-light source exciting system. A focusing lens assembly and an air chamber are sequentially arranged on a light path of laser pulses output by a nanosecond-pulse laser. The laser pulses are focused into the air chamber through the focusing lens assembly, light emitted by generated plasma flame is collected by an optical collecting device, and a high-brightness pulse white-light source is obtained. The collected white light of the high-brightness pulse white-light source exciting system can be used for spectral analysis, imaging, illumination, photoetching, transfer printing and other fields. The high-brightness pulse white-light source exciting system achieves white light output which is short in pulse time, high in instantaneous strength, stable in time and spectral property, and wide in spectral region.

Description

technical field [0001] The invention relates to an excitation system of a high-brightness pulsed white light source, which belongs to the field of wide-spectrum light sources. Background technique [0002] The pulsed light source with wide spectral range, high intensity and high brightness (also known as high brightness pulsed white light source) has a wide range of application values ​​in many fields of spectral analysis, imaging and lighting, as well as lithography and transfer printing. The main point of high-brightness pulsed white light source, as the name suggests, lies in the instantaneous high-intensity pulse and the white light output in a wide spectral range. [0003] The commonly used high-brightness pulsed white light source is Xe flash lamp. Its principle is the plasma discharge luminescence generated by high-voltage and high-current instantaneous discharge. Its wide-spectrum white light emission comes from the complex and diverse excimer excited state luminesce...
