Application Note: Laser Diode Power Supply Transient Response Under Typical Laser Diode Fault Conditions
When a laser fails, it can suffer catastrophic damage if the power supply does not have a failsafe. This application note documents tests conducted with three different types of power supplies to determine how they respond to a typical failure scenario.
Hulett presents the old-world problem that plagues today's LED measurements. Learn what it is, why it matters, and what you can do about it.
