Abstract
High power diode lasers, operating in long pulse width mode, require high reliability in the medical aesthetic application. In this study, we have developed a sophisticated high-performance diode laser device. For diode laser (LD) chips with a 1.5 mm cavity length at a wavelength of 808 nm, the thermal resistance is approximately 0.3 K/W. The thermal rollover power in continuous mode reaches 268 W, which is 40% higher than conventional MCCs with direct chip bonding. In quasi-continuous mode with 20 ms at 10 Hz, the maximum power reaches 345 W, marking a 15% enhancement compared to MCCs with direct chip bonding.
