Abstract
We reported our proof-of-concept investigation in developing an arrayed and passively -switched laser. In the investigation, we used a Dammann grating to diffract the pumping light from a 808 nm laser diode into pump beam array, and then used this pump array to pump a monolithic laser crystal standing with a saturable absorber inside a simple plano–plano resonator. As a result, arrayed and nanosecond laser pulses were emitted. The laser-diode-pumped monolithic solid-state laser incorporated with a Dammann grating is promising for application in high-peak-power and multipoint pulse ignition of an automobile engine.
