    Abstract: A laser apparatus for producing a laser light beam can include a gain medium; a pump light source to provide a pump light beam to the gain medium; a first reflector disposed between the first gain medium and the first pump light source and spaced apart from a gain portion of the first gain medium; a second reflector; and an output coupler. The first reflector is substantially reflective to the laser light beam and substantially transmissive to the pump light beam. The first and second reflectors and the output coupler define a folded beam path having a first portion and a second portion. The first portion of the beam path extends from the first reflector to the second reflector through the gain medium and the second portion of the beam path extends from the first reflector to the output coupler through the gain medium. The first and second beam paths define, within the gain medium, a non-zero folding angle. Optionally, the laser apparatus can include a second pump light source that can pump the same, or a second, gain medium.

    Abstract: Laser radiation delivered to a treatment area causes vaporization of a substantially greater volume of tissue than the volume of residual coagulated tissue. The laser radiation may have a wavelength of about 300 nm to about 700 nm, may be used with a smoke suppressing inigant, may have an average irradiance greater than about 5 kilowatts/cm 2 , and may have a spot size of at least 0.05 mm 2 . A laparoscopic laser device, for use with an insufflated bodily cavity, may include an elongate body adapted for insertion into an insufflated bodily cavity. A laser energy delivery element, at the distal end of the elongate body, may be coupleable to a source of tissue-vaporization-capable laser energy and capable of delivering laser energy along a laser energy path extending away from the laser energy delivery element. A smoke-suppressing liquid pathway, extending along the elongate body to an exit opening at the distal end, may be coupleable to a source of a smoke-suppressing liquid. The smoke- suppressing liquid is directed generally along the laser energy path. A remote visualization device may be used to view along the laser energy path.

    Abstract: The invention concerns a device with an elongated optical guide (1) and pumping means, for producing by stimulated emission an optical signal (4) under the effect of an optical pumping by a pump wave (6), the stimulated emission from the active elements of the guide having been excited by the pump wave. The invention is characterized in that the single-crystal guide having a core (3) doped with active elements and a non-doped peripheral cladding (2) enables the pump wave to be guided and confined in its entire volume, the optical signal (4) produced in the core being freely propagated (8),the optical indices of the core and the cladding being sufficiently close to avoid guiding in the doped core. In an implementation mode, the guide has a shorter length than the length of an optical signal Raleygh length in the guide. The device can be implemented in impulse optical amplifiers or laser oscillators.

    Abstract: A chip-shaped laser medium (12) is side pumped to improve mode matching between the pumping energy (50) and lasing mode volume (36). The chip thickness (44) and laser medium doping level can be designed and controlled to ensure adequate pumping coupling efficiency. The chip shape can also be employed to provide greater chip surface areas (22) for cooling the laser medium (12). The laser pumping package (70), gain module (10 1 ), and chip-shaped design can be scalable to offer higher pumping power and high output power. Different orientations of the gain modules (10 1 ) with respect to each other can be used to provide better lasing mode quality.
