Smoke evacuation system for removal of aerosolized chemical compounds and biological fine particles produced during laser treatment of tissue. The rapid smoke evacuation is achieved by coupling a low capacity vacuum pump to a vacuum valve and a vacuum reservoir to create very high flow rate for very short durations. The opening time of the valve could at least partially overlap the laser pulse duration.
