Abstract
Bei einem Verfahren und einer Vorrichtung zur Frequenzkonversion sowie bei einer Verwendung eines optisch-parametrischen Kristalls (5) ist vorgesehen, dass der optisch-parametrische Kristall (5) zum Anpassen einer Pumpschwelle von Pumpstrahlung (2) mit einer Phasenanpassungsperiodizität ausgebildet ist, die ein Vielfaches einer doppelten Kohärenzlänge des optisch-parametrischen Prozesses ist. Dadurch ist mit verhältnismäßig günstigen Herstellungskosten auch bei einer verhältnismäßig großen Wechselwirkungslänge eine schmale Verstärkungsbandbreite erzielt.In a method and a device for frequency conversion and when using an optical parametric crystal (5), it is provided that the optical parametric crystal (5) is designed to adapt a pumping threshold of pump radiation (2) with a phase matching periodicity which is a multiple a double coherence length of the optical parametric process. As a result, a narrow gain bandwidth is achieved with relatively low production costs even with a relatively large interaction length.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine Vorrichtung zur Frequenzkonversion der eingangs genannten Arten und eine Verwendung eines optisch-parametrischen Kristalls anzugeben, bei denen sich bei einem für einen hohen Wirkungsgrad guten Anpassen einer Pumpschwelle eines optisch-parametrischen Kristalls und einer Pumpleistung von Pumpstrahlung auch bei einer kostengünstigen Herstellung sowohl eine hohe resonatorinterne Feldstärke als auch eine schmale Verstärkungsbandbreite ergeben. The invention has for its object to provide a method and a device for frequency conversion of the aforementioned types and a use of an optical parametric crystal, in which good for a high efficiency adjusting a pumping threshold of an optical parametric crystal and a pump power of Pump radiation result in a cost-effective production both a high resonator field strength and a narrow gain bandwidth.

Diese Aufgabe wird bei einer Verwendung eines optisch-parametrischen Kristalls der eingangs genannten Art erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches 6 gelöst. This object is achieved with a use of an optical parametric crystal of the type mentioned according to the invention with the characterizing features of
Dadurch, dass erfindungsgemäß der optisch-parametrische Kristall eine Phasenanpassungsperiodizität aufweist, die ein ungerades Vielfaches, beispielsweise das Dreifache, der doppelten Kohärenzlänge des optisch-parametrischen Prozesses ist, lässt sich ein derartiger Kristall aufgrund der größeren Strukturen verhältnismäßig kostengünstig herstellen und weist bei einer verhältnismäßig großen Wechselwirkungslänge eine hohe resonatorinterne Feldstärke, aber auch trotz einer im Vergleich zu einem optisch-parametrischen Kristall mit einer nur einem Einfachen der doppelten Kohärenzlänge des optisch-parametrischen Prozesses entsprechender Phasenanpassungsperiodizität erster Ordnung relativ hohen, mit zunehmender ungerader Ordnungszahl ansteigenden Pumpschwelle eine schmale Verstärkungsbandbreite auf. Because the optical parametric crystal according to the invention has a phase matching periodicity which is an odd multiple, for example three times twice the coherence length of the optical parametric process, such a crystal can be produced relatively inexpensively due to the larger structures and has a relatively large phase Interaction length a high intra-cavity field strength, but also in spite of a relatively high compared to an optical parametric crystal with a just twice the coherence length of the optical parametric process corresponding phase matching periodicity of first high, with increasing odd atomic number of pumping threshold a narrow gain bandwidth.
