<p>In the cutting with a laser beam there are in the target point material changes which affect the repeated application and efficiency of the laser beam. Provisions are made to send a thermal laser beam (4) and a photodisruptive laser beam (5) and to combine the two into one output beam having a common optical axis, in which the photodisruptive laser beam (5) and the thermal light beam (4) travel simultaneously. The different laser types cause different effects on target point, whereby a higher rate of disruption is achieved by concentrating pressure and heat in the same space and brief time span at the target point to provide execution of incisions in substances. Vascularized tissue is ablated without bleeding by the combined use of the argon (2) and the Nd:YAG laser (3).</p> |
