Diode-pumped Lasers - RP Photonics

The compactness of the pump source, the power supply and the cooling arrangement makes the whole laser system much smaller and easier to use. Diode pumping makes it possible to use a very wide range of solid-state gain media for different wavelength regions, including e.g. upconversion lasers. For many solid-state gain media, the lower brightness of discharge lamps would not be sufficient.

Pump Laser - an overview | ScienceDirect Topics

The control electronics for the pump lasers in the amp-pair require a stable voltage source that is provided by a chain of Zener diodes driven directly by the system line current. Most laser drivers use a linear power supply, which limits the maximum laser drive current to the available line current of the overall cable system.
