A system for providing multi-wavelength laser includes an optical splitter arranged to split light received from a pulsed laser source into at least a first light beam and a second light beam a first optical regulator arranged to adjust a wavelength of the first light beam and to output the adjusted first light beam a second optical regulator arranged to introduce a time delay to the second light beam and to output the delayed second light beam and an optical combiner arranged to combine the first adjusted light beam and the second delayed light beam, and to output a combined light beam.
