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 measurement signal based on the portion of the at least one laser pulse detected by the energy-sensing device; and
a controller comprising a calibration module configured to:
generate at least one categorized calibration table based on a spectrum matrix;
determine calibration parameters for the at least one categorized calibration table based on the measurement signal;
interpolate the calibration parameters of the at least one categorized calibration table; and
cause the at least one laser cavity to generate at least one calibrated laser pulse based on the at least one categorized calibration table with interpolated calibration parameters.
