abstract
We show that it is possible to improve the efficiency of a laser system by adding a classical heat engine cycle to the laser gas which can remove both thermal and vibrational energy from the gas. Rapid pulsed CO2 laser-gas expansion cycle engine and a continuous CO2 laser-Brayton cycle engine are analysed to determine practicality. Combined laser-mechanical efficiencies can approach 80% for operational systems. 2004 Taylor & Francis Group, LLC.
