摘要： An improved gas laser is disclosed. The laser has a support tube to support and to maintain the alignment of the optical resonator structure. The gas lasing medium is used within the support tube to maintain the tube at a substantially constant temperature above the ambient. Furthermore, an active temperature controller is disclosed. The temperature controller maintains the gas lasing medium in the support tube at a substantially constant temperature. An active pressure controller is also disclosed. The active pressure controller uses a pressure sensor, an electronic processor, and a motor-driven needle valve to maintain the pressure of the gas lasing medium in the laser within the desired operating pressure range. The laser can also be switched in operation from a continuous mode to a pulsing mode. An active power control system is disclosed wherein the power output of the laser, through an active feedback loop is maintained at the desired level. Because the optical resonator structure is light weight, it can be mounted on a mechanical assembly. The beam is delivered to a desired location by the mechanical assembly. Finally, a distributive lasing system comprising a centralized pump delivering the lasing medium to a plurality of remotely located optical resonator structures is disclosed.

摘要： A radiation delivery module (8) includes a body (48) supportable on a patient's skin and defines a skin surface plane generally aligned with the patient's skin surface (40). A radiation source (22) is mounted to the body and produces a beam (34) of tissue-damaging radiation directed transverse to and at the skin surface plane. The radiation beam creates a radiation spot (42) having a length (36) and a width (44) at the skin surface plane, the length being at least about 5 to 10 times the width. A number of scanned diode laser radiation sub-sources (64) each directing a radiation beam component (66) at the radiation spot may be used. The radiation source may include a rod lens as a focusing optical element. The radiation delivery module may also include a radiation source translator (18) so that the radiation spot moves in a direction generally perpendicular to the length of the radiation spot.

摘要： A medical laser system and related methods of monitoring optical fibers to determine if an optical fiber cap on the optical fiber is in imminent danger of failure. The laser system includes a photodetector for converting returned light from the optical fiber cap to an electronic signal for comparison to a trigger threshold value known to be indicative imminent fiber cap failure. The returned light can be the main laser treatment wavelength, an auxiliary wavelength such as an aiming beam or infrared wavelengths generated by a temperature of the optical fiber cap. In the event the electronic signal reaches the trigger threshold value, the laser system can be temporarily shut-off or the power output can be reduced.

摘要： A hair removal device (22) includes a cooling surface (34) which is used to contact the skin (6) prior to exposure to hair tissue-damaging laser light (74) passing from a radiation source (36) through a recessed window (46). The window is laterally offset from the cooling surface and is spaced apart from the cooling surface in a direction away from the patient's skin to create a gap between the window and the skin. The window preferably includes both an inner window (46) and an outer, user-replaceable window (48). The laser-pulse duration is preferably selected according to the general diameter of the hair.

摘要： A method and apparatus for determining the quality of a multimode laser beam (10). In the preferred embodiment, the apparatus includes a lens (32) for creating a transformed or imaged waist from the input beam. The location of the transformed beam waist and its diameter are then determined. These steps can be carried out by chopping the beam using a rotating hub (34) having apertures (36,38) for selectively passing the beam. Preferably, one of the apertures has a pair of 45.degree. knife edges 40,42). The transmission of the beam past the knife edge is monitored by a detector (30). In operation, the lens focal position is varied while the transmission of the beam past the knife edge is monitored in order to locate and measure the diameter of the transformed waist. The diameter of the beam at one other known location is measured. A processor then calculates beam quality by fitting these measurements to a mathematical model. Once the quality of the beam is calculated, the location of the original beam waist and its diameter can be derived. Once all of the beam parameters are derived, the propagation characteristics of the beam can be predicted.

摘要： A laser resonator system including an optical resonator whose side wall has an orifice through which gas may enter the resonator's interior, and may subsequently flow along the resonator's longitudinal axis. An elongated electrode (which preferably is an anode) is positioned at the orifice in electrical communication with the entering gas so that the projection of the electrode's tip on the plane of the orifice does not coincide with the center of the orifice. In a preferred embodiment, the electrode's longitudinal axis is aligned generally perpendicular to the plane of the orifice. In another preferred embodiment, two such electrode-orifice pairs are provided and are separated by a small distance along the resonator's axis. The orifice positions are preferably on opposite sides of the resonator, so that they are separated by an azimuthal angle substantially equal to 180.degree. with respect to the resonator tube's longitudinal axis. The relative position and orientation of each electrode-orifice pair results in an improved, flatter gas velocity profile downstream from the orifice.
