Description
nischen Lösungsmittel, wie ζ. Β. Dimethylformamid (DMF). In der Küvette 3 befinden sich 2wei plattenfönnige Elektroden 6 und 7, die -jich in einem geringen Abstand, größenordnungsmäßig etwa 1 mm parallel gegenüberstehen. Die beiden Elektroden sind beispielsweise aus rostfreiem Stahl hergestellt. An den Elektroden 6 und 7 liegt eine hohe Gleichspannung, die nur durch die Durchbruchsfeldstärke des verwendeten Lösungsmittels begrenzt ist.niche solvents, such as ζ. Β. Dimethylformamide (DMF). In the cuvette 3 there are two disk dryers Electrodes 6 and 7, which -jich at a small distance, on the order of about 1 mm face parallel. The two electrodes are made of stainless steel, for example. To the Electrodes 6 and 7 have a high DC voltage, which is only due to the breakdown field strength of the used Solvent is limited.
Beim Stromfluß durch die Flüssigkeit 5 werden an der Anode in einer Elektrodenreaktion nach dem Schema DPA - ee -*- DPA® Kationen erzeugt, während entsprechend an der Kathode gemäß dem Schema DPA -Jr e® -»■ DPA® Anionen erzeugt werden. Kationen und Anionen werden durch das Feld in entgegengesetzten Richtungen transportiert und erzeugen beün Aufeinandertreffen in einer Rekombmaüonsreaktion nach dem Schema DPA* + DPA« -* DPA* + DPA Moleküle im ersten angeregten Smgulettzustand, von wo aus ein Laserüberg^ng zum Grundzustand erfolgen kann. Die entstehende Laserstrahlung tritt dann in Richtung des Pfeiles 8 aus dem optischen Resonator aus. . ,When current flows through the liquid 5 at the anode in an electrode reaction according to the scheme DPA - e e - * - DPA® cations are generated, while correspondingly at the cathode according to the scheme DPA -Jr e® - »■ DPA® anions are generated. Cations and anions are transported through the field in opposite directions and, when they meet in a recombination reaction according to the scheme DPA * + DPA «- * DPA * + DPA, produce molecules in the first excited smgulet state, from where a laser transition to the ground state can take place. The resulting laser radiation then emerges from the optical resonator in the direction of arrow 8. . ,
Es ist ohne weiteres klar, diaß eine nach dem neuen Verfahren arbeitende Vorrichtung auch zum Anregen kleiner Volumina geeignet ist, die mit Entladungsblitdampen nicht mehr sinnvoll angeregt werden können.It is readily apparent that one after the other Method-working device is also suitable for exciting small volumes, using discharge flash lamps can no longer be sensibly stimulated.
