Powering laser diode systems Power electronics design rules which will help you save time and avoid frustration LD and LED similarities and differences Laser diode as an electrical load. Laser diode driving requirements Ideal and real sources of electrical energy Requirements for LD powering. Graphical presentation of LD and LDD Cooperative operation Primary and secondary sources of electrical energy Secondary electrical sources High frequency switchmode DC to DC converters in LD systems Utilization of converter parasitic elements Specifics of transformers operating in HF VTOV converter HF switchmode LD driver topology Powering LDD from the battery and the 1 phase AC line. Power factor correction. Soft switching in the boost type converters Powering industrial laser diode systems LD drivers based on other topologies Passive switchmode voltage to power (VTOP) converters in laser systems Powering other components of LD systems This Tutorial Text discusses the competent design and skilled use of laser diode drivers (LDDs) and power supplies (PSs) for the electrical components of laser diode systems. It is intended to help power electronic design engineers during the initial design stages: the choice of the best PS topology the calculation of parameters and components of the PS circuit and the computer simulation of the circuit. Readers who use laser diode systems for research production and other purposes will also benefit. The book will help readers avoid errors when creating laser systems from ready made blocks as well as understand the nature of the mystical failures of laser diodes (and possibly prevent them)
