Filed:

Mar 30, 2001

Appl. No.:

09/822700

Inventors:

Duane Donald Smith - Louisville CO
Glenn Taylor Bennett - Boulder CO
AnnMarie Louise Oien - Boulder CO
Timothy William Monarski - Lafayette CO

Assignee:

Coherent Technologies, Inc. - Boulder CO

International Classification:

H01S 330

US Classification:

359334

Abstract:

A noncollinear pumped solid state Raman laser or amplifier has a pump laser that transversely or noncollinearly pumps a solid state Raman gain material, with an intensity sufficient to produce a stimulated Raman laser output beam. The pump beam and the Raman beam are noncollinear when the Raman beam travels completely across the pump beam within the Raman gain material, or where the Raman beam completely separates physically, at some location in the pumped Raman gain material, from a virtual beam, which is collinear to the pump beam axis, and which has the same entrance spot size and beam divergence as the Raman beam. The device enhances the pump laser beam spatial homogenization to improve the wavefront smoothness and propagation performance from the pump beam to the Raman beam. Other configurations of the device have a plurality of mirrors, or prisms to fold the pump beam to cause the pump beam to pass through the Raman material a plurality of times, which increases the energy transferred from the pump beam to the Raman beam.

Duane Smith - Glendale AZ, US

International Classification:

A61B 90/70

Abstract:

Disclosed herein, a power supply may be recharged with a generally used system. In various embodiments, cleaning systems may be used to affect a generator to cause the generator to charge a power supply. Such charging systems may be used without the need for separate or specialized power charging systems. A charging source or system may, therefore, also charge a power supply without requiring additional steps.
