Abstract

Ein Verfahren zum Betrieb einer Laserlichtquelle, insbesondere zum Scannen in einem konfokalen Laserscanmikroskop, wobei die Laserlichtquelle (3) über ein Netzteil mit Strom versorgt wird, ist zur Verlängerung der Lebensdauer der Laserlichtquelle (3) und zur Reduzierung der Betriebskosten dadurch gekennzeichnet, daß die Laserlichtquelle (3) im wesentlichen nur während der Strahlnutzzeit, vorzugsweise während der Datenaufnahme, mit der erforderlichen Leistung betrieben wird. Bei Verwendung einer pulsierenden Laserlichtquelle ist die Strahlnutzzeit, insbesondere die Datenaufnahme, im wesentlichen mit dem Emissionszyklus der Laserlichtquelle synchronisiert (14).
