Abstract: The medical laser user interface of the present invention generally comprises a medical laser unit and a control system. The medical laser unit includes an optical probe for delivering laser light to a patient's tissue. The control system controls operation of the medical laser unit. Specifically, the control system provides a foot pedal system that enables the user to switch between the delivery of a first wavelength of laser light and a second wavelength of laser light through depression of a foot pedal. In a first embodiment, a single foot pedal can be used to toggle the wavelengths, where as in a second embodiment two foot pedals can be use, one for the first wavelength and one for the second wavelength. The two wavelengths provided include a wavelength for vaporization of tissue and a wavelength for coagulation.

Abstract: In a method, a laser pump module is set to a first power mode and pump energy is output at a first power level through the activation of a first subset of laser diodes. Laser light is emitted from a gain medium at the first power level in response to absorption of the pump energy. An operator input corresponding to a power mode setting is received. The laser pump module is switched to a second power mode and pump energy is output at a second power level through the activation of a second subset of the laser diodes. Laser light is emitted from the gain medium at the second power level in response to absorption of the pump energy.

Abstract: A pump module comprises a power source, a plurality of laser diodes, a controller and light combining optics. The laser diodes each have an activated state and a deactivated state. The laser diodes receive current from the power source and output light when in the activated state and do not receive current from the power source when in the deactivated state. The controller switches the plurality of laser diodes from a first power mode, in which a first subset of the laser diodes is in the activated state, to a second power mode, in which a second subset of the laser diodes is in the activated state, responsive to a power mode setting. The light combining optics are configured to combine the light from the activated laser diodes and output the combined light as pump energy. A laser system comprises a pump module and a gain medium. The pump module is configured to output pump energy having a wavelength that is within a wavelength range of 874-881 nm.

Abstract: 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.

Abstract: A system and method for authenticating an optical fiber for use with a medical laser system includes a medical laser unit, an optical fiber, and a memory device. The laser unit is typically specific to a certain medical procedure and is under the operation of a control system. The optical fiber is operably coupled to the laser unit and includes a probe tip for position proximate laser-targeted tissue. The memory device is associated with the optical fiber, e.g., as an RFID tag embedded in fiber or a smart card operational with the fiber, and is configured to allow the control system of the laser unit to access information embedded in the memory device so that the optical fiber may be authenticated as suitable to operate with the laser unit.
