Modular Unstable Ring Resonator With Multiple Output Couplers
US Patent:
H99, Aug 5, 1986
Filed:
May 24, 1984
Appl. No.:
6/613481
Inventors:
Robert W. Jones - Huntsville AL
Cha Caso - Huntsville AL
James F. Perkins - Huntsville AL
Cha Caso - Huntsville AL
James F. Perkins - Huntsville AL
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
H01S 308, H01S 3081
US Classification:
372108
Abstract:
A modular unstable ring resonator utilizing several independent gain modules is used to obtain output of a multiple set of mutually coherent beams. Additionally, rigorous mutual coherence is maintained even when the system operates on more than one longitudinal mode or/and on more than one gain transition; specific frequency-control elements are eliminated; satisfactory operation is possible with one or more gain-medium modules disabled. Each segment of the ring resonator's optical path may contain a laser gain medium, an output mirror, and a beam expander for continuously circulating a portion of the system flux while also coupling out a portion of the flux from each output mirror. The plural outputs may be used individually or collectively.
Unstable Optical Resonators With Tilted Spherical Mirrors
US Patent:
4239341, Dec 16, 1980
Filed:
Oct 30, 1978
Appl. No.:
5/956137
Inventors:
Charles M. Cason - Huntsville AL
James F. Perkins - Huntsville AL
Robert W. Jones - Huntsville AL
James F. Perkins - Huntsville AL
Robert W. Jones - Huntsville AL
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
H01S 3083
US Classification:
350294
Abstract:
Tilted spherical mirrors are used as a means of achieving asymmetric magnification (M. sub. x. noteq. M. sub. y) in collimated-output unstable resonators which obviate fabrication difficulties associated with non-spherical mirrors. By suitable choice of rather large tilt angles of spherical mirrors and mirror separation, simultaneous "confocality" can be achieved in x-z and y-z planes to the lowest order.
Phase Locked Rf Linac Free Electron Laser
US Patent:
4748629, May 31, 1988
Filed:
Dec 10, 1987
Appl. No.:
7/131476
Inventors:
George R. Edlin - Huntsville AL
Robert W. Jones - Huntsville AL
James F. Perkins - Huntsville AL
Robert W. Jones - Huntsville AL
James F. Perkins - Huntsville AL
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
H01S 300
US Classification:
372 2
Abstract:
A radio frequency linear acceleration free electron laser is provided by ing the pulses in such a time delay manner to phase lock the device and produce phase correlation between the laser pulses.
