Pump In laser technology, a pump is a device or energy source used to supply energy to the gain medium within a laser system, initiating the process of stimulated emission and laser light generation. Pumps can take various forms depending on the type of laser system, including flashlamps, electrical discharges, diode lasers, or other optical sources capable of delivering energy to the laser medium.
The pump supplies energy to the gain medium to raise atoms or molecules to higher energy states, creating a population inversion necessary for laser emission. Pumps play a critical role in determining the efficiency, power output, and operating characteristics of laser engraving systems, influencing their performance and engraving capabilities. |
