Technical content

Features

 Micro-channel cooled laser bar  For continuous wave (cw) and quasi continuous wave (qcw) operation  Highly reliable semico nductor material with minimal life time of 10,000 h, typically >50,000 h  Low thermal resistance  Low smile (< 3 µm) and low mechanical tolerances  Coolant inlet/outlet at bottom.  Optional manifold for easy usage

Applications

 Pumping of solid state lasers  Direct industrial applicat ions (soldering, surface treatment,…)  Medical applications  Printing applications Safety Advices Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 60825-1 “Safety of laser products”.

Liegt die Wellenlänge höher als im Testprotokoll spezifiziert, so weist dies auf einen schlechten thermischen Kontakt und eine thermische Überlastung der Laserdiode hin. Bevor der Laserbetri eb weitergeführt wird, muss der thermische Kontakt verbessert werden. Die zentrale Emissionswellenlänge 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. 3) Das Anlegen einer Spannung in Sperrrichtung der Laserdiode muss ausgeschlossen werden. Reverse voltage has to be excluded. 4) Die Lebensdauer der wassergekühlten Hochleistungs-Diodenlaser wird maßgeblich von der Qualität des Kühlwassers beeinflusst. Durchfluss, Druck, Leitwert (Reinheit) und Temperatur des Kühlwassers müssen 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, c onductivity (purity), temperature and water particle filter must be defined properly. As coolant de-ionized (DI-) water has to be used.
