​​​​​DiPOLE amplifier concept drawing

 


The Diode Pumped Optical Laser for Experiments (DiPOLE) laser architecture provides a scalable concept design for efficient, high energy, high repetition rate diode pumped laser systems. This established and proven concept is based on a cryogenically cooled, multi-slab amplifier head.  

The DiPOLE laser is a scaled down prototype laser system designed for operation at 10 Hz pulse repetition rate. At 140 K, the system gener​ated 10.8 J of energy in a 10 ns pulse at 1029.5 nm when pumped by 48 J of diode energy at 940 nm, corresponding to an optical to optical conversion efficiency of 22.5%. This represents the highest pulse energy obtained from a cryo cooled Yb laser to date and the highest efficiency achieved by a multi-Joule diode pumped solid state laser system.  

More recently the DiPOLE conept has been applied using two amplifier heads resulting in 100J of laser radiation within a 10ns pulse at a 10Hz repeition rate. This represents the highest pulse energy obtained from a cryo cooled Yb laser to date and the highest efficiency achieved by a multi-Joule diode pumped solid state laser system. ​
