What is Diode Pumped Solid State Laser (DPSSL)

A Diode Pumped Solid State Laser (DPSSL) is a laser system that uses semiconductor laser diodes to excite a solid state gain medium such as Nd or Nd. DPSSL technology offers high efficiency, excellent beam quality, compact design and reliable performance for industrial, medical, scientific and communication applications. This page explains Diode Pumped Solid State Laser (DPSSL) basics and its function in fiber optic systems. It is a small laser device. It contains a diode paired with an optical crystal.

Applications of Diode Pumped Solid State Lasers

DPSSL devices find application in a variety of fields, including:

• Biotechnology Instrumentation • Graphics and Imaging • Semiconductor manufacturing

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.
