| Number | Title | Issue Date |
| 5253261 | Gas laser solenoid and cooling apparatus A high temperature laser solenoid incorporates a combination of thermally and electrically insulating components to replace and to exceed the operating limits of epoxy encapsulation which solenoid is used in cooperation with a mechanically driven cooling ... | 10/12/1993 |
| 5099491 | Laser gas replenishment system A gas replenishment system for a gas laser utilizes a gas metering device between a gas reservoir and the gas laser tube which operates at a pressure below the gas reservoir pressure. The metering device incorporates a body of gas entrapping material. The... | 03/24/1992 |
| 4961202 | Single line laser and method A gas laser tube assembly terminates at one end with a directly affixed selectively coated curved mirror and at the opposite end with a directly affixed selectively coated half-Littrow prism oriented such that one hundred percent (100%) purity, single lin... | 10/02/1990 |
| 4930136 | Segmented air cooled laser tube A plurality of thin wall ceramic-metal segments are brazed together to form a gas laser tube assembly. Within each segment there is mounted a refractory metal ferrule with a central hole. The series of holes formed in the ferrules define the discharge bor... | 05/29/1990 |
| 4892497 | Method for assembly of laser mirrors A gas laser tube is fitted with internal mirrors only and no windows. The laser tube is processed by heating the tube with the ends open in a vacuum oven to drive out contaminating substances. The mirrors are installed by cold welding after the tube has b... | 01/09/1990 |
| 4803697 | Cold welded laser mirror assembly A gas laser tube is fitted with internal mirrors only and no windows. The laser tube is processed by heating the tube with the ends open in a vacuum oven to drive out contaminating substances. The mirrors are installed by cold welding after the tube has b... | 02/07/1989 |
| 4774713 | Segmented laser tube structure A plurality of thin wall ceramic-metal segments are brazed together to form a gas laser tube assembly. Within each segment there is mounted a ferrule with a central hole. The series of holes formed in the ferrules define the discharge bore and gas return ... | 09/27/1988 |
| 4504951 | High speed switching power supply for a light controlled laser system A high speed switching power supply for a laser system is disclosed. In the preferred embodiment, proportional-plus-derivative feedback of the emitted light controls the duty cycle of the MOS-FET switching transistor to vary the d.c. voltage level applied... | 03/12/1985 |
| 4477907 | Low power argon-ion gas laser An argon-ion laser achieves low output power by using a plasma guide and mirror configuration which restricts lasing action to a portion of the resonator cavity at relatively high conversion efficiency.... | 10/16/1984 |
| 4434493 | Argon-ion gas laser cathode construction An improved argon-ion gas laser utilizes a dispenser-type cathode and within the cathode shroud mounts a preignition electrode and a heat shield enabling the cathode to be operated efficiently and within a 900°-1050° C. temperature range over an extende... | 02/28/1984 |
| 4385390 | Laser bypass inhibitor An improved bypass inhibitor attached to but not constituting part of the laser bore assembly of a ceramic gas laser tube having main and gas bypass bores comprises a ceramic disc, one side of which is both metal bonded to the tube and formed with metal s... | 05/24/1983 |
| 4380077 | Segmented ceramic bore laser A laser tube made of electrically insulating ceramic material, e.g., BeO, is formed of dry pressed and fired segments brazed together and with a chamfer or stepped area at the end of each segment adapted to interrupt the bore so as to prevent the establis... | 04/12/1983 |
| 4017745 | Switching regulator power supply An improved switching regulator circuit is adapted for use with switch regulators in which more than one transistor is operated in parallel to provide a higher output current than normally obtained. Each transistor is operated with a separate inductor or ... | 04/12/1977 |
