Abstract
A gradual ramp-up of output power in a medical laser prevents rapid temperature rise at a fiber tip of a laser handpiece when residual contamination from a prior medical procedure remains on the fiber tip after an extended cooling period. The gradual ramp-up eliminates effects of an acoustic shock wave resulting from the rapid temperature rise to prevent damage to fiber and optical components in the laser device.
