Figure: Depicts a Diode Pumped Solid State Laser

As shown in the figure, this is an end-pumped type of laser. It features a plane perpendicular to the PN junction of the laser diode.

Diode Pumped Solid State Laser Function in Fiber Optic System

Diode pumped solid state lasers can serve as an optical source for fiber optic communication. They produce a stable and specific wavelength of light that can be launched into an optical fiber for data transmission. The diode laser pumps the solid state gain medium(typically a crystal) to amplify light.
