​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;

  • Ability to easily generate and modify temporal pulse shapes
  • Automatic beam alignment system
  • An Adaptive optic system 

The amplifier head contains 4 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.

Work has recently started to enable the DiPOLE beam to be transported into a second laboratory to extend current capabilities including an investigation into laser shock peening.


Parameters list:
  • Pulse energy 10J​
  • Wavelength 1030nm
  • Pulse duration variable between 2 and 10 ns
  • Repetition rate 10 Hz
