摘要： A lasing medium (3) and a Raman medium (20) share a common optical cavity. The lasing medium (3) projects laser light into the Raman medium (20) and, when a threshold intensity within the Raman medium is reached, the Raman medium absorbs the laser light and re-radiates coherent light at a shifted frequency. Optical elements within the system provide an optical cavity for the lasing medium and a second cavity for the Raman medium.

摘要： A pulsed laser system may include a Raman fiber that is configured to act as multiple wavelength Raman laser. The fiber is configured to receive a pulsed input beam from an input source and convert the input beam to an output beam having narrow band outputs at first and second frequencies v1 and v2.

摘要： Disclosed herein is a coherent dynamically controllable narrow band light source (10), comprising a first sub-light source (12), said first sub-light source being electrically controllable such as to generate controllable time-dependent intensity patterns of light having a first wavelength, a Raman active medium (30) suitable to cause Raman scattering of light having said first wavelength, a second sub-light source (20) capable of emitting light with a second wavelength, said second wavelength being longer than said first wavelength, and an optical fiber or wave guide, wherein said light emitted by said first and second sub-light sources traverses a length of said optical fiber (30) or wave guide in a feed-forward configuration to facilitate a non-linear wavelength conversion step involving said Raman-active medium. At least one of said first and second sub-light sources (12, 20) has a coherence length longer than 0.05 mm, preferably longer than 0.5 mm and most preferably longer than 2 mm.

摘要： A mid- to far-infrared solid state Raman laser system comprising a resonator cavity comprising: an input reflector adapted to be highly transmissive for light with a first wavelength in the range of about 3 to about 7.5 micrometers for admitting the first beam to the resonator cavity; and an output reflector adapted to be partially transmissive for light with a second wavelength greater than about 5.5 micrometers for resonating the second wavelength in the resonator and for outputting an output beam, the input reflector further being adapted to be highly reflective at the second wavelength for resonating the second wavelength in the resonator; and a solid state diamond Raman material located in the resonator cavity for Raman shifting the pump beam and generating the second wavelength.

摘要： By compensating polarization mode-dispersion as well chromatic dispersion in photonic crystal fiber pulse compressors, high pulse energies can be obtained from all-fiber chirped pulse amplification systems. By inducing third-order dispersion in fiber amplifiers via self-phase modulation, the third-order chromatic dispersion from bulk grating pulse compressors can be compensated and the pulse quality of hybrid fiber/bulk chirped pulse amplification systems can be improved. Finally, by amplifying positively chirped pulses in negative dispersion fiber amplifiers, low noise wavelength tunable seed source via anti-Stokes frequency shifting can be obtained.

摘要： The invention provides a laser system (100) wherein the output may be selected from two or more different wavelengths of output laser light. The system (100) comprises a laser capable of having at least two different wavelengths of laser light resonating in the cavity (105) simultaneously. One of the frequencies is generated by a Raman crystal (135) which shifts the frequency of light generated by the lasing medium (125). A tunable non-linear medium (140), such as LBO, is provided in the cavity for selectively frequency converting at least one of the at least two different wavelengths of laser light. The conversion may be SHG, SFG or DFG for example. A tuner (145) is provided.to tune the non-linear medium to select the particular wavelength to convert. Temperature tuning or angle tuning of the non-linear medium can be used. A Q switch (130) may also be provided in the cavity. The output laser beam can be used for treatment, detection or diagnosis of a selected area on or in a subject, and can b used in ophthalmological and dermatological fields.
