DiPOLE Prototype
02 Apr 2012



A cryogenically gas cooled, diode-pumped, solid-state laser system


​​​​​​​​​​​DiPOLE laboratory​​​​​​​

​DiPOLE is the first diode-pumped, solid-state laser (DPSSL) system based on the DiPOLE concept. Initially conceived as a prototype to prove the DiPOLE concept, it has since become a useful test bed for continued research and development for the next generation systems.

Currently, DiPOLE has the following features which are of interest to future systems:

•The ability to easily generate and modify temporal pulse shapes;
•An automatic beam alignment system;
•An adaptive optic system.

The amplifier head contains four laser gain medium disks which are​ Ytterbium-doped Yttrium-Aluminium-Garnet (Yb-YAG) ceramic. These disks are pumped from both sides by diode lasers and are cooled using a flow of helium gas which is cooled by liquid nitrogen.
The DiPOLE beam can be transported into a second laboratory to allow for further experiments to be carried out including:
Laser shock peening​ experiments;​
Second harmonic generation​ experiments [1];
•Damage testing experiments.
