The laser system(100) comprises an oscillator (110), the active material responsive to first laser radiation such that in response to the first laser radiation, the active material emits photons, a diode pump (115) comprising at least one laser diode array arranged to provide the first laser radiation to the active material to excite the active material to emit the photons, and a pulse generator (330) for generating first pulsed laser radiation at a first wavelength and having a micro-macro pulse structure, and a conversion stage (120) coupled to the oscillator stage to receive the first pulsed laser radiation (117), the conversion stage configured to amplify the first pulsed laser radiation and convert at least some of the amplified pulsed laser radiation (125) to a second wavelength, the conversion stage providing second pulsed laser radiation at the second wavelength and having the micro-macro pulse structure, wherein the micro-macro pulse structure includes a plurality of macro-pulses having a duration (T2) on the millisecond scale, each of the plurality of macro-pulses comprising the envelope of a plurality of micro-pulses having a pulse duration (T3) on the picosecond scale. |
