Werte beziehen sich auf die Standardbetriebsbedingung 30 W Ausgangsleistung, 20 C Kuhlwassertemperatur und 0.6 l/min Kuhlwasserfluss. Values refer to standard operating conditions of 30 W output power, 20 C coolant temperature and 0.6 l/min coolant flow. Die zentrale Emissionswellenlange muss beim spezifizierten Strom kontrolliert werden. Liegt die Wellenlange hoher als im Testprotokoll spezifiziert, so weist dies auf einen schlechten thermischen Kontakt und eine thermische Uberbelastung der Laserdiode hin. Bevor der Laserbetrieb weitergefuhrt wird, muss der thermische Kontakt verbessert werden. Die zentrale Emissionswellenlange schiebt mit 0,3 nm/K. Check the emission wavelength at the specified current. A much longer wavelength than specified in the test protocol indicates bad thermal contact and thermal overload of the diode laser. Then the thermal contact has to be improved before continuing laser operation. The emission wavelength shifts with 0.3 nm/K. Das Anlegen einer Spannung in Sperrrichtung muss ausgeschlossen werden. Reverse voltage has to be excluded. Modell zur Bestimmung des thermischen Verhaltens bzgl. des Schwellstroms: Model for the thermal behavior of threshold current: Ith(T2) = Ith(T1) x exp (T2 - T1)/T0 Temperatur und Fluss des Kuhlwassers beeinflussen die Ausgangsleistung, die zentrale Emissionswellenlange und die Lebensdauer. Betauung muss ausgeschlossen werden. Coolant temperature and flow influences output power, emission wavelength and lifetime. Condensation has to be excluded. Als Kuhlwasser muss vollstandig entionisiertes (VE-) Wasser verwendet werden mit einer maximalen Partikelgroe von 5 m und einem maximalen Leitwert von 4 S/cm. As coolant de-ionized (DI-) water has to be used with a maximum particle size of 5 m and a maximum conductivity of 4 S/cm.
