D. when specific temperature rise higher than when setting value, change continuous light beam into pulsed light beam, when temperature continues to continue to rise, reduce pulse frequency or reduce pulse duty factor, in like manner, the time increase gradually pulse duty factor or rising pulse frequency and change pulsed light beam into continuous light beam lower than setting value when temperature;
E. when carrying out water-cooled, synchronously attract reflux to start cooling flushing, reclaim the cooling water of cooling package.
10. a kind of multifunctional laser therapeutic combined method based on the described system of claim 1 according to claim 9, described method further comprises: it is to utilize the mode of negative pressure of vacuum to reclaim cooling water that described cooling flushing attracts reflux, and control to discharge flow and the flow velocity of water with effusion meter, when discharge water is greater than the cooling water of input, controls the discharge water yield and make to discharge water and input water all the time in poised state.
