Abstract
Variable waveform output in surgical laser is achieved by controlling power into a solid-state laser cavity. A control circuit is used to coordinate pulse energy, pulse frequency, and pulsewidth into a solid-state laser cavity to achieve a user desired waveform output. An Insulated Gate Bipolar Transistor (IGBT) or similar solid-state transistor switching device under the direction of a control circuit is used to switch energy into the solid-state laser cavity thereby modulating the pulse frequency and pulsewidth. The pulse energy is varied by varying the charge across the capacitor bank which sends energy through the IGBT to the solid-state laser cavity. By having the ability to vary the laser's output pulse frequency, pulsewidth, and pulse energy, multiple tissue effects can be achieved using one solid-state laser cavity.
