摘要： A laser oscillator which can keep distributions of pressure of a laser medium inside of a plurality of discharge tubes constant while making the laser medium circulate without stagnating. The laser oscillator is comprised of a first discharge tube, second discharge tube, first light guide, laser medium flow path, and blower. A flow resistance of a laser medium flow path between the blower and the first discharge tube and a flow resistance of the laser medium flow path between the blower and second discharge tube are the same as each other. A flow resistance of the laser medium flow path between the blower and a first end of the first light guide and a flow resistance of the laser medium flow path between the blower and a second end of the first light guide differ from each other.

摘要： An excimer laser has a laser chamber containing a laser gas and including an electrode assembly for firing gas discharge pulses in the laser gas for pumping the laser. The electrode assembly includes two elongated electrodes, one or both of which is partially covered by a ceramic foam. The electrodes are arranged to provide a discharge gap between the electrodes. The ceramic foam on an electrode serves to damp acoustic disturbances and resulting refractive index disturbances in the gas that occur as a result of firing a gas discharge pulse in the discharge gap.

摘要： The present invention provides a slab type gas laser for generating an excellent output laser beam having substantially Gaussian intensity distribution when it is focused by the lens. For this end, a pair of cylindrical electrodes 11, 12 of different diameter are disposed concentrically by way of spacers 13 and laser medium is filled in the gap between the two cylindrical electrodes 11, 12 to define a straight slab 1. Disposed at one end of the straight slab 1 is a ring-shaped trick mirror M1. Also disposed at the center of the one end of the straight slab 1 is an output mirror M2 to pass a part of the light and to reflect a part of the remaining light. On the other hand, disposed at the other end of the straight slab 1 is a w-axicon mirror M3. The relationship between the center offset Xm and the center position X0 of the trick mirror is set to Xmnull1.1 X0.

摘要： A compact laser includes an inner quartz tube defining a central bore coaxially disposed within an outer quartz tube sealed with respective end cap assemblies. Each end cap assembly is bonded to a respective end of the outer quartz tube and includes an electrode which at least partially surrounds or is proximate to a corresponding end of the inner quartz tube. Each end cap assembly also supports a mirror element and includes means for adjusting the angular orientation of the mirror elements to bring them into mutually parallel optical relationship. An opening is provided at at least one end of the inner tube proximate to the corresponding electrode which serves to provide a path of lower resistance to direct the region of gas discharge away from the mirror element so that the resulting sputtering is substantially restricted to a region that does not contain the mirror element. The end cap assemblies are fabricated of one or more materials which are thermally compatible and bondable with quartz. The invention provides means for safeguarding the mirror elements against sputtering of material from the electrodes; means for providing a very compact and stable laser which does not employ an external resonator; and compact means for adjusting the laser mirrors.

摘要： An enhancement of approximately 100 of stimulated emission over spontaneous emission of the CVI 182 Angstrom line was obtained in a recombining magnetically confined plasma column. The plasma was formed by focusing a CO.sub.2 laser beam on a carbon disc. A magnetic solenoid produced a strong magnetic field which confined the plasma to the shape of a column. A single thin carbon blade extended parallel to the plasma column and served to make the column axially more uniform and also acted as a heat sink. Axial and transverse measurements of the soft X-ray lasing action were made from locations off-set from the central axis of the plasma column. Multiple carbon blades located at equal intervals around the plasma column were also found to produce acceptable results. According to another embodiment 10 a thin coating of aluminum or magnesium was placed on the carbon disc and blade. The Z of the coating should preferably be at least 5 greater than the Z of the target. Measurements of the soft X-rays generated at 182 Angstroms showed a significant increase in intensity enhancement.

摘要： The subject invention is related to a new and improved bore assembly for use with a gaseous ion laser. Each bore assembly is mountable to a heat conducting member located within the tube. The heat conducting member is provided with a central opening and is connected at the periphery thereof to the inner surface of the tube. The bore assembly of the subject invention includes a discharge confining element having a central channel and formed from a sputter-resistant material such as graphite. An outer support member is provided which is disposed about at least a portion of the discharge confining element and is brazed to the heat conducting member in a manner to mechanically constrain the discharge confining element. During assembly, the opening of the channels of the discharge confining elements are coaxially aligned. During operation of the laser, the mechanically constrained discharge confining element will be heated and expand radially into the outer support member until thermal equilibrium is achieved thereby defining a thermally conductive pathway for cooling the laser.
