摘要： The invention relates to a saturable absorber structure (10) with multiple-layer epitaxial heterostructure absorbers. Typically the structure comprises first absorber layers of a quantum well semiconductor QW-material, which has a nonlinearly on radiation intensity dependent optical absorption; first contacting layers of a first optically transparent semiconductor material against a surface or surfaces of said first absorber layers; and a first Bragg-reflector (23). The first contacting layers have lattice fit or pseudomorphism with said first absorber layers. The absorber layer (13, 13a, 13b) of the QW-material has a thickness (S) of at maximum 60 nm. Further, said first optically transparent semiconductor material of the contacting layer (14, 14a, 14b, 14c) is a reactive R-material, which semiconductor material contains two or more main components, at least one dopant (M2), and at least one metallic alloying element (M1) substituting one of said main components and enhancing the incorporation of said dopant(s). The metallic alloying element has a concentration of at least 50 atomic-% of that main component it substitutes. This way the charge carriers originating in said QW-material of the first absorber layer has a first recombination time at maximum 100 picoseconds determined by recombination of the charge carriers at sites of said dopant(s), thus forming a fast saturable absorber.

摘要： An optical device comprises: an active semiconductor region (130), for providing gain to signal light (170) passing through said active region (130); a signal-light reflector (120), for reflecting the signal light (170) through the active region (130) in a direction out of the plane of the active region (130); a pump-light reflector (120), the pump-light reflector (120) being arranged to reflect pump light so as to form a standing wave (160) in the device; and an absorber (191) that absorbs light at a wavelength of the signal light. The absorber (191) is arranged at a position in the device at which there is no or substantially no pump light.

摘要： The invention is directed to an apparatus and method for oscillator start-up control, and more particularly to an apparatus and method for overdriving a laser to obtain mode-lock operation. The oscillator with start-up control has a lasing medium mounted on a base. A laser pumping source is mounted on the base for inducing a laser beam from the lasing medium. A mode-lock detection device(64) is mounted about the base. An overdrive circuit (61) is coupled with the mode-lock detection and signal processing device for determining mode-lock status of the oscillator. The overdrive circuit overdrives the pump source (62) when the oscillator (63) is not in mode-lock status.

摘要： A passive Q switch. The inventive Q switch (230) includes a first wedge (232) of material adapted to absorb electromagnetic energy. The first wedge (232) has a first thickness on a first end thereof and a second thickness on a second end thereof diametrically opposite the first end. The first wedge (232) has a first surface connecting the first and second ends and a second surface (236) connecting the first and second ends. The second surface (236) is slanted relative to the first surface. A second wedge of material (234) is included in the inventive passive Q switch (230). As per the first wedge (232), the second wedge (234) has a first thickness on a first end thereof and a second thickness on a second end thereof diametrically opposite the first end. The second wedge has a first surface connecting the first and second ends and a second surface (238) connecting the first and second ends. The second surface (238) is slanted relative to the first surface. The second surface (236) of the first wedge (232) is mounted in optical alignment with the second surface (238) of the second wedge (234) and in a plane parallel thereto. In the illustrative embodiment, the wedges (232, 234) are made of chromium:yttrium aluminum garnet (Cr+2:YAG) and mounted to allow the first and second wedges to translate relative to each other while maintaining a constant distant 'd' between the second surfaces thereof. The inventive Q switch allows for a variable thickness and lasing hold-off in a passive arrangement.

摘要： A glass fiber laser system (20) includes a laser resonator cavity (22) having a resonant path (23) and an erbium-doped glass fiber lasing element (28) with an emitted coherent light beam of from about 1.5 to about 1.6 micrometers within the laser resonator cavity (22). A pumping light source (32) directed into an input end of the glass fiber lasing element (28) optically pumps the lasing element (28) to emit light. A passive Q-switch (38) lies along the resonant path (23) within the laser resonator cavity (22). The Q-switch (38) is formed of a host material having a concentration of uranium ions therein, so as to be a saturable absorber of the light emitted by the lasing element. The Q-switch (38) is preferably a uranium-doped fluoride crystal such as U:CaF
2 , U:SrF
2 , or U:BaF
