摘要： A Kerr Mode Locked ("KLM") laser is configured with a resonant cavity. The gain medium, selected from polycrystalline transition metal doped II-VI materials ("TM:II-VI), is cut at a normal angle of incidence and mounted in the resonant cavity so as to induce the KLM laser to emit a pulsed laser beam at a fundamental wavelength. The pulses of the emitted laser beam at the fundamental wavelength each vary within a 1.8 - 8 micron ("μm") wavelength range, have a pulse duration equal to or longer than 30 - 35 femtosecond ("fs") time range and an average output power within a mW to about 20 watts ("W") power range. The disclosed resonant cavity is configured with a plurality of spaced apart reflectors, two of which flank and are spaced from the gain medium which is pumped to output a laser beam at a fundamental wavelength and its higher harmonic wavelengths. The gain medium is mounted on a translation mechanism operative to controllably displace the gain medium along a waist of the laser beam. The displacement of the gain medium causes redistribution of a laser power between a primary output at the fundamental wavelength and at least one secondary output at the higher harmonic wavelength.

摘要： A supercontinuum source using diamond as the supercontinuum material is disclosed that works at higher average powers than previous sources. The thermal properties of diamond allow continuum to be generated directly from an oscillator at high repetition rates. The diamond does not need to be translated even at multi-Watt power levels. This diamond continuum source can be based on a single filament and thus possesses excellent stability and phase coherence.

摘要： Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device positioned along the optical axis of the resonator.

摘要： A broadband source, including associated devices that may incorporate the broadband source, which makes use of at least one, preferably two or more broad fluorescence spectra in combination from one or more species of transition metal ions doped in one or more material bodies. The bodies are selected from crystalline, glass-ceramic, glass, or polymer-organic materials. The broadband source or devices can generate a very broad fluorescence spectrum. The combined spectrum preferably spans a wavelength range of about 500 nm to 600 nm to 700 nm, and having an intensity that does not deviate from an average intensity by more than about 10 dB, over a range or portion of the near infrared region.

摘要： A high-power semiconductor diode laser or array of semiconductor diode lasers (14) optically end-pumps a compact, tunable, solid-state laser (28) with a pumping beam (74) well-matched to the absorption bandwidth and mode volume (78) of the solid-state laser (28). Tilted birefringent plates (210) positioned within the solid-state resonator cavity (16) are employed to control the spectral bandwidth and wavelength output of the waveguide pumping beam (204). Infrared output (100) generated by such a solid-state laser (28) is coupled into a nonlinear waveguide (200) and converted to visible output (206) through the process of second-harmonic generation.
