Description
Die Erfindung bezieht sich auf einen von Laserdioden gepumpten Festkörperlaser mit longitudinalem Einmodenbetrieb im sichtbaren Wellenlängenbereich gemäß dem Gattungsbegriff des Anspruchs 1.The invention relates to a solid-state laser pumped by laser diodes with longitudinal single-mode operation in the visible wavelength range according to the preamble of claim 1.
Ein solcher Laser ist durch die DE 40 41 131 A1 bekannt. Der hier offenbarte Festkörperlaser ist als Mikrokristall-Laser anzusprechen, welcher bei einer mechanisch einfachen Ausführung sowohl eine Frequenzverdopplung und Frequenzmischung, als auch eine Abstimmung und Modulation der Grundwellenlänge und zweiten Harmonischen bei effizientem "Single Frequency" Betrieb gewährleistet.Such a laser is known from DE 40 41 131 A1. This here disclosed solid-state laser can be addressed as a micro-crystal laser, which in a mechanically simple version both frequency doubling and frequency mixing, as well as tuning and modulating the Basic wavelength and second harmonic with efficient "single frequency" Operation guaranteed.
Ein Mikrokristallaser mit internem frequenzverdoppelnden Kristall ist aus der EP 04 55 383 A2 bekannt und weiterhin ist der US-Zeitschrift: "Opt. Letters", Vol. 12, No. 12, Dec. 1987, S. 999-1001 ein Mikrokristallaser zu entnehmen, der eine piezoelektrische Frequenzabstimmung des Lasers aufweist. Eine resonatorinterne Frequenzverdopplung ist aus diesem Stand der Technik nicht ersichtlich.A micro crystal fiber with an internal frequency doubling crystal is off EP 04 55 383 A2 and the US magazine: "Opt. Letters ", Vol. 12, No. 12, Dec. 1987, pp. 999-1001 a microcrystalline fiber refer to the piezoelectric frequency tuning of the laser having. An internal doubling of the frequency is from this state the technology is not apparent.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, unter Beibehaltung der Eigenschaften des vorgenannten Mikrokristall-Lasers, einen solchen zu schaffen, mit dem eine erweiterte Abstimmung und Modulation der grund- und frequenzverdoppelten oder frequenzgemischten Wellenlänge ermöglicht wird.The present invention has for its object, while maintaining the properties of the aforementioned micro crystal laser create with which an advanced tuning and modulation of the basic and frequency-doubled or frequency-mixed wavelength is made possible.
Diese Aufgabe wird durch die im Patentanspruch aufgezeigten Maßnahmen gelöst. Nachfolgend ist ein Ausführungsbeispiel beschrieben und in der einzigen Figur der Zeichnung skizziert, die ein Schemabild eines halbmonolithischen, abstimmbaren Mikrokristall-Lasers im sichtbaren Wellenlängenbereich veranschaulicht.This object is achieved by the measures indicated in the claim solved. An embodiment is described below and in the sketched single figure of the drawing, which is a schematic image of a semi-monolithic, tunable micro-crystal laser in the visible wavelength range illustrated.
Das in der Figur skizzierte Ausführungsbeispiel zeigt einen Resonator des vorgenannten Festkörperlasers 10, der aus einem Laserkristall 11, der als einseitig einkoppelnder Spiegel S1 ausgebildet ist und einem nichtlinearen Kristall 12 gebildet ist, der einseitig als Auskoppelspiegel S2 ausgebildet ist, wobei die Kristalle 11 und 12 nach Schliff, Beschichtung und Montage die Ausbildung einer Resonatormode gewährleisten, wie dies in der vorgenannten Druckschrift bereits ausgeführt ist. Mit 14 ist die Pumplicht- Laserdiode bezeichnet.The exemplary embodiment outlined in the figure shows a resonator of the aforementioned solid-state laser 10 , which is formed from a laser crystal 11 , which is designed as a mirror S1 which is coupled in on one side, and a non-linear crystal 12, which is formed on one side as a coupling-out mirror S2, the crystals 11 and 12 After grinding, coating and assembly, ensure the formation of a resonator mode, as has already been stated in the aforementioned publication. With 14 the pump light laser diode is designated.
