Zusammenfassung
Die Idee zu einem diodengepumpten Festkörperlaser wurde schon kurz nach der Entdeckung des Diodenlasers [1.1] Anfang der sechziger Jahre beschrieben. Damals beobachtete R. Newman die starke Fluoreszenz des Nd3+-Ions bei 1.06 μm in einem CaWO4-Kristall, den er mit Rekombinationsstrahlung von einem GaAs-pn-Übergang anregte [1.2]. Das Potential solcher Laser erkennend, wies er in seiner Publikation auf die Konsequenzen seines Experiments hin:
“The potential advantages of this type of pumping source for a laser are several. The small size and simple structure of the diodes will make possible a direct coupling of the pumping radiation to the laser without any complex optics. This in turn will greatly reduce the size and cost of the functional devices. The efficiency of conversion of input power to output power, both as regards the pump source and the internal conversion of energy within the laser, may permit continuous power output several orders of magnitude higher than is presently possible”.
