摘要： A method and apparatus for obtaining laser action between an upper energy level and a lower energy level of a gaseous medium, which comprises populating the upper energy level to some degree (short of achieving a conventional inverted population) by any suitable pumping means, and thereafter establishing an inverted population by transiently and selectively depumping the lower energy level such as by exposing the medium to an intense source of radiation which selectively causes the transformation of the lower energy level species to some other energy level. Thus, a thermally pumped/optically depumped gas laser system is produced.

摘要： An apparatus and method are provided for producing an ultrashort pulsed output beam. A 694 nm pump beam from a first GaN semiconductor laser diode pumped, Q-switched ruby laser is directed into at least one amplifier that includes a broadband gain element doped with trivalent chromium ions (Cr3+). A spectrally linearly chirped low-intensity seed pulse from a master oscillator is directed into the at least one optically pumped amplifier to produce an amplified linear chirped pulsed output beam. A 694 nm second pump beam from a second GaN semiconductor laser diode pumped, Q-switched ruby laser is directed into a power amplifier that also includes a broadband gain element doped with trivalent chromium ions (Cr3+). The amplified linear chirped pulsed output beam is directed into the optically pumped power amplifier to produce a high energy linear chirped pulsed output beam which is then directed into a pulse compressor to produce the ultrashort pulsed output beam.

摘要： A new class of lasers is provided that can be pumped by conventional high-power, multi-mode, broadband 1-D and 2-D laser diode arrays, where the pumped laser gain medium comprises an atomic vapor of one the alkali elements (Li, Na, K, Rb or Cs), buffered with a mixture of rare-gas (He, Ar, Kr, Ne or Xe) and selected molecular gases. The alkali atom gain medium is pumped at a wavelength matching the wavelength of the 2S1/2-2P3/2 electric-dipole-allowed transition (the D2 transition). After kinetic relaxation of pump excitation to the excited 2P1/2 electronic level, laser emission takes place on the 2P1/2-2S1/2 transition (the D1 transition).

摘要： A pulse compression and prepulse suppression apparatus (10) for time compressing the output of a laser (14). A pump pulse (46) is separated from a seed pulse (48) by a first polarized beam splitter (20) according to the orientation of a half wave plate (18). The seed pulse (48) is directed into an SBS oscillator (44) by two plane mirrors (22, 26) and a corner mirror (24), the corner mirror (24) being movable to adjust timing. The pump pulse (46) is directed into an SBS amplifier 34 wherein SBS occurs. The seed pulse (48), having been propagated from the SBS oscillator (44), is then directed through the SBS amplifier (34) wherein it sweeps the energy of the pump pulse (46) out of the SBS amplifier (34) and is simultaneously compressed, and the time compressed pump pulse (46) is emitted as a pulse output (52). A second polarized beam splitter (38) directs any undepleted pump pulse 58 away from the SBS oscillator (44).

摘要： The invention relates to apparatus and methods for producing high intensity laser radiation generation which is achieved through an optical amplifier-storage ring design. One or two synchronized, counterpropagating laser pulses are injected into a regenerative amplifier cavity and amplified by gain media which are pumped repetitively by electrical or optical means. The gain media excitation pulses are tailored to efficiently amplify the laser pulses during each transit. After the laser pulses have been amplified to the desired intensity level, they are either switched out of the cavity by some switch means, as for example an electro-optical device, for any well known laser end uses, or a target means may be injected into the regenerative amplifier cavity in such a way as to intercept simultaneously the counterpropagating laser pulses. One such well known end uses to which this invention is intended is for production of high density and temperature plasmas suitable for generating neutrons, ions and x-rays and for studying matter heated by high intensity laser radiation.

摘要： A diode pumped solid state laser is provided which includes a ruby crystal optical gain medium and a high bandgap semiconductor laser diode (LD) or light emitting diode (LED) pump source to directly optically pump the gain medium. The high-bandgap semiconductor LD or LED is a semiconductor device whose chemical composition is chosen to provide output radiation at an approximate wavelength of ˜405 nm. The ruby crystal produces laser output at the relatively short wavelength of ˜694 nm.
