Diode laser serves as the energy source for fiber laser owing to its unique advantages over wavelength, brightness and fiber coupled output mode. It is an integral part of fiber laser. Any diode laser for this purpose is called fiber laser pump source.

Diode laser can serve as energy source for solid laser owing to such advantages as high reliability and high photoelectric conversion efficiency. It is a product providing such matched parameters as wavelength, brightness and output mode for various working mediums. It is an integral part for solid laser. The diode laser for this purpose is also called solid laser pump source.
