Abstract
High efficiency laser performance of 2 mm diameter and 20 mm long Nd: YAG c rystal rod transversely pumped by laser diode array is presented. Using the directly side-coupled geometry enclosed by cylindrical pump cavity plated with gold, we obtained long pulse energy of 4.6 mJ corresponding to optical -to-optical slope efficiency of 37%. The complete solid-state Nd:YAG laser is described to be simple, compact and highly efficient. Q-switching of the laser is also reported. (C) 2001 Elsevier Science Ltd. All rights reserved .
