Werte beziehen sich auf die Standardbetriebsbedingung 600 W cw Ausgangsleistung, 25C Kuhlwassertemperatur und 3,5 l/min Kuhlwasser-Durchflussmenge. Values refer to standard operating conditions of 600 W cw output power, 25C coolant temperature and 3.5 l/min coolant flow rate. 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 Uberlastung 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 inefficient or inadequate cooling and thermal overload of the diode laser. Then the cooling has to be improved before continuing laser operation. The emission wavelength shifts with 0.25 nm/K. Das Anlegen einer Spannung in Sperrrichtung der Laserdiode muss ausgeschlossen werden. Reverse voltage has to be excluded. Die Lebensdauer der wassergekuhlten Hochleistungs-Diodenlaser wird mageblich von der Qualitat des Kuhlwassers beeinflusst. Durchfluss, Druck, Leitwert (Reinheit) und Temperatur des Kuhlwassers mussen angemessen definiert sein. Es darf nur entionisiertes Wasser verwendet werden. An essential criterion for the lifetime of actively cooled high-power diode lasers is defined in using the right cooling water. Water flow, dynamic pressure, conductivity (purity), temperature and water particle filter must be defined properly. As coolant de-ionized (DI-) water has to be used.
