LASER SYSTEM Abstract of the Disclosure A laser system adapted for ophthalmological use includes a closed spherical pump cavity having a diffuse reflecting surface, and a laser crystal and an exciting flashlamp are mounted in non- parallel fashion in the cavity The laser crystal is configured in an unstable resonator by a concave rear mirror and a convex front output mirror. A Q-switch is interposed between the crystal and one of the mirrors to permit Q-switched and non-Q-switched operating modes. A low power, continuous output, visible light laser is directed through the rear mirror and the laser crystal to provide a pilot beam for aiming and focussing. The laser outputs are directed to a focussing system through a slit lamp biomicro- scope, and both are directed into the eye of a patient. A laser power supply includes a plurality of capacitors arrayed in banks and controlled by a microprocessor to deliver pulses of preselec- ted voltage to the flashlamp singly or sequentially to produce single pulses, bursts of pulses, or repetitive pulses on command. A control system also operates the Q-switch in synchronism with the flashlamp, when Q-switching is desired. The system may be run in a thermal mode in which the laser crystal is stimulated by closely spaced repeated lamp flashes to cause the stimulated electron population inversion to be maintained. The resulting long train of pulses within a predetermined time-power envelop closely mimics a continuous beam end produces the thermal physio- logical effects which are desirable for some laser surgical proce- dures. In the Q-switched mode, the combination of microprocessor control, a short optical pumping cavity, an unstable resonator configuration, and a small diameter, short length, high gain crystal produce very narrow pulses of high intensity, high beam quality, and precise duration, spacing, and energy.
