Abstract
A medical laser device is described that generates a laser beam controllable with presets as to pulse duration, pulse repetition rate, power and energy per pulse. The device also provides presets with respect to water and air outputs. Parametric values for power, pulse duration, pulse repetition rate, and energy per pulse as well as for water and air settings may be programmed by an end user and stored as presets.

A method of using a power supply to generate dual pulse outputs for an electromagnetic energy output device, the method comprising:
- providing a first high voltage output —of about 1200-1500 volts from the power supply, the first high voltage output being capable of driving a first pulse-forming network that has a capacitor of about 30-70 μF and an inductor of about 30-70 μH and is configured to generate a first pulse output;
- and
- providing a second high voltage output —of about 200-500 volts from the power supply, the second high voltage output being capable of driving a second pulse-forming network that has a capacitor of about 300-600 μF and an inductor of about 800-1200 μH and is configured to generate a second pulse output.
A method of using a power supply to generate dual pulse outputs for an electromagnetic energy output device, the method comprising:
- Providing a plurality of high voltage outputs from the power supply including at least a first voltage of about 200-500 volts and a second voltage of about 1200-1500 volts;
- and
- Providing a plurality of pulse-forming networks having capacitors of about 30-70 μF and 300-600 μF and inductors of about 30-70 μH and 800-1200 μH, wherein the plurality of high voltage outputs drives the plurality of pulse-forming networks with signals differing in one or more of duration and power.
An apparatus, comprising:
- a device having a single power supply capable of supplying a first high potential output at a first potential level and a second high potential output at a second potential level, the first potential level being higher than the second potential level;
- a pumping source;
- a first pulse-forming network having a capacitor of about 30-70 μF and an inductor of about 30-70 μH and being capable of receiving the first high potential output, the first pulse-forming network further being capable of driving the pumping source with a first signal;
- and
- a second pulse-forming network having a capacitor of about 300-600 μF and an inductor of about 800-1200 μH and being capable of receiving the second high potential output, the second pulse-forming network further being capable of driving the pumping source with a signal differing from the first signal in one or more of duration and power.
