Abstract
A method of generating light with a laser-driven light source includes generating a CW sustaining light and propagating the CW sustaining light to a gas filled bulb comprising an ionizing gas. A pump light is generated. A Q-switched laser crystal is irradiated with the generated pump light, thereby generating pulsed laser light. The pulsed laser light is propagated to the gas filled bulb comprising the ionizing gas so as to generate a CW plasma that emits light. The light generated by the CW plasma in the gas filled bulb is detected. The pump light is controlled so as to extinguish the pulsed laser light after the light generated by the CW plasma is detected.
