Abstract

A medical laser system is disclosed for ablation/resection/coagulation of unwanted tissue, including parenchymal lung resection to facilitate/accelerate growth/wound healing. System comprises laser energy sources and conveying means, optical fiber. A diode laser source emits above 1330 nm, at least 50 Watts, through an optical fiber onto target tissue. Wavelength, 1340 nm is preferred. Wavelength ranges 1330-1390 nm and 1450-1550 nm, are also useful. Additionally a wavelength, between 800-1100 nm, can be used. Wavelength differences maximize beam quality. Two radiation sources emit simultaneously from fiber's distal end. One emits at ˜1320 nm and the other emits at ˜1340 nm or ˜1360 nm with maximum total output power of 60 W or larger. Preferably, the ratio of the power levels is fixed at 1:1.5 and output power is the sum of individual lasers. High beam quality and power density system combines emissions from a diode laser and a fiber laser.
