| 摘要 |
<p>This invention relates to a solid state laser system where the optical output of an array of gas discharge lamps (1) are optically filtered (2) and the resultant optical output fibre bundle (3) coupled into a laser rod medium (4) which is fluid cooled (5). Above its lasing threshold, laser rod (4) is excited by the output of the laser diode array (6) via optical fibre bundle (7). In this manner, the optically filtered output of the gas discharge lamps (1) is used to bring the laser rod (4) up to lasing threshold at relatively low overall efficiency whilst above threshold excitation is achieved with the light output of laser diode array (6) which can either be modulated or single pulse switched.</p> |
