Availability for Non-Exclusive, Exclusive, or Partially Exclusive 
Licensing of U.S. Patent Concerning a Liquid Immersed Pumped Solid 
State Laser

AGENCY: Department of the Army, DoD.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: In accordance with 37 CFR 404.6 and 404.7, announcement is 
made of the availability for licensing of the invention set forth in 
U.S. Patent No. 6,760,351 entitled ``Liquid Immersed Pumped Solid State 
Laser,'' issues on July 6, 2004. The United States Government, as 
represented by the Secretary of the Army, has rights in this invention.

ADDRESSES: Office of Research and Technology Applications, SDMC-RDTC-
TDL (Ms. Susan D. McRae), Bldg. 5220, Von Braun Complex, Redstone 
Arsenal, AL 35898.

FOR FURTHER INFORMATION CONTACT: Ms. Joan Gilsdorf, Patent Attorney, e-
mail: [email protected], (256) 955-3213 or Ms. Susan D. 
McRae, Office of Research and Technology Applications, e-mail: 
[email protected]; (256) 955-1501.

SUPPLEMENTARY INFORMATION: The invention pertains to temperature 
control of solid state lasers. A liquid immersed pumped solid state 
lasing system includes a light source and a lasing element spaced from 
the light source. The light source and the lasing element are mounted 
in an insulated container. The top of the container is open for 
inputting a clear cryogenic cooling liquid into the container to 
totally immerse the light source and the lasing element in the liquid. 
Heat transfer occurs by conduction from the light source and the lasing 
element to the liquid, thereby cooling the light source and the lasing 
element to cryogenic temperatures. The container has a window for the 
output of laser light. A plurality of electrical leads that are 
superconducting at cryogenic temperatures are attached to the light 
source. When the leads are connected to a power supply outside the 
container, the light source directs light on the lasing element so that 
the lasing element is excited and transmits a light output through the 
window.
