Study of Laser Power Converters based on GaN for High Power Applications
Wide bandgap semiconductors can improve the efficiency of the high power laser transmission (HPLT) technology due to the reduction of series resistance and intrinsic entropic losses. We present modeled laser power converters (LPCs) made of GaN for a wide range of power densities. Results show that GaN-based LPCs can improve the efficiency of the technology up to 84% at 100 W/cm2. Using this material can broaden the range of HPLT applications due to its high resilience to extreme environmental conditions.
