Diode pumped Nd:YAG laser development [PDF]

open access: yes
A low power Nd:YAG laser was constructed which employs GaAs injection lasers as a pump source. Power outputs of 125 mW TEM CW with the rod at 250 K and the pump at 180 K were achieved for 45 W input power to the pump source.

Utilisation of Low Temperature Heat Sources in Absorption Refrigeration Systems

open access: yes, 1998
In this paper, a detailed thermodynamic analysis of a two-stage absorption refrigeration system using binary mixture lithium bromide-water as a working fluid is presented. The coefficients of performance for different operating temperatures have been calculated and illustrated in diagrams.
