US Patent 9757199 Surgical laser systems and laser lithotripsy techniques

A surgical laser system includes a first laser source, a second laser source, a beam combiner and a laser probe. The first laser source is configured to output a first laser pulse train comprising first laser pulses. The second laser source is configured to output a second laser pulse train comprising second laser pulses. The beam combiner is configured to combine the first and second laser pulse trains and output a combined laser pulse train comprising the first and second laser pulses. The laser probe is optically coupled to an output of the beam combiner and is configured to discharge the combined laser pulse train.
