Laser diodes application to photodynamic therapy

Experimental technique and devices

Semiconductor lasers with 665 nm wavelength and optical power of 2 W in continuous mode at room temperature have been developed. Application of GalnP/GaAs quantum well structure and original emitter design allowed to obtain a high temperature and spatiotemporal stability of emission intensity, high lifetime and low noise level. Developed optical devices are highly suitable for application in medical systems to photodynamic therapy.
