Claim Text:
1. A laser assembly comprising: a fundamental laser configured to generate laser light pulses having a fundamental frequency disposed within a fundamental frequency bandwidth; a pulse dividing element configured to divide each laser light pulse into a pair of corresponding sub-pulses including a first sub-pulse and a second sub-pulse; at least one monolithic device configured such that the first sub-pulse of each pair of corresponding sub-pulses is converted into a first stretched sub-pulse having a positive chirp, and configured such that the second sub-pulse of each pair of corresponding sub-pulses is converted into a second stretched sub-pulse having a negative chirp; and a frequency mixing module configured to mix each first stretched sub-pulse with its corresponding said second stretched sub-pulse such that said mixing generates sum frequency light including sum frequency pulses having frequencies equal to two times the fundamental frequency.
