1. A medical laser system for outputting laser pulses, the system comprising:
at least one laser cavity configured to generate at least one laser pulse;
a rotating mirror configured to receive and reflect the at least one laser pulse;
a beam splitter configured to receive and reflect a portion of the at least one laser pulse received from the rotating mirror;
an energy-sensing device configured to detect the portion of the at least one laser pulse;
an energy measurement assembly configured to generate a feedback signal based on the portion of the at least one laser pulse detected by the energy-sensing device;
a controller configured to generate an electronic control pulse based on the feedback signal received from the energy measurement assembly to generate at least one adjusted laser pulse; and
a memory storing at least one spectrum matrix that correlates a plurality of frequencies specified on a first axis and a plurality of pulse energies on a second axis to an average power output of the medical laser system,
wherein the medical laser system is configured to calibrate one or more laser modes based on the feedback signal and the at least one spectrum matrix.
