Passiv gekuhlter Diodenlaser-Barren, 50 W cw bei 808 nm Passively Cooled Diode Laser Bar, 50 W cw at 808 nm SPL MN81G2
Vorlaufiges Datenblatt / Preliminary Data Sheet
Besondere Merkmale * Laserbarren auf passiv gekuhlter Warmesenke, kein Kuhlwasser erforderlich * Fur Dauerstrich- (CW) und quasi-kontinuierlichen Betrieb (QCW) * Zuverlassiges Halbleiter-Material mit Mindest-Lebensdauer von 10.000 h, typischerweise >50.000 h * Geringer thermischer Widerstand * Geringer smile (< 2,5 m), geringe mechanische Toleranzen Anwendungen * Pumpen von Festkorperlasern * Direkte industielle Anwendungen (Loten, Oberflachenbehandlung,...) * Medizinische Anwendungen * Druckanwendungen Sicherheitshinweise Je nach Betriebsart emittieren diese Bauteile hochkonzentrierte, nicht sichtbare InfrarotStrahlung, die gefahrlich fur das menschliche Auge sein kann. Produkte, die diese Bauteile enthalten, mussen gema den Sicherheitsrichtlinien der IEC-Norm 60825-1 behandelt werden Typ Type SPL MN81G2 Anzahl Barren Bar count 1 Features * Laser bar mounted on passive mount, no water required * For continuous wave (cw) and quasi continuous wave (qcw) operation * Highly reliable semiconductor material with minimum life time of 10,000 h, typically >50,000 h * Low thermal resistance * Low smile (< 2.5 m) and low mechanical tolerances Applications * Pumping of solid state lasers * Direct industrial applications (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".

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 0,28 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 0.28 nm/K. Das Anlegen einer Spannung in Sperrrichtung der Laserdiode muss ausgeschlossen werden. Reverse voltage has to be excluded.
