Power supply circuit analysis of pulsed semiconductor laserPulsed semiconductor lasers have the advantages of high peak power and small size, and are widely used in the fields of laser ranging, lidar and free space laser communication.

Various techniques for switching power supplies to reduce lossesThe efficiency of PWM switching power supply without special loss control technology is lower than that of switching power supply with loss control technology. For switching power supplies that have no problem with heat dissipation, such as some off-line power supplies, the efficiency may be satisfactory. But for portable power supplies and devices requiring small size, greater efficiency must be sought.
