Applications
Recommended for continuous wave (cw)- Pumping of solid-state and fiber lasers Direct material processing Heating, illumination 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 found in IEC 60825-1 “Safety of laser products”.

1) Alle Kenn- und Grenzwerte beziehen sich auf Pulsmessungen (1 μs Pulsbreite bei 4 kHz Wiederholfrequenz) an unmontierten Barren. Die Erzielung der spezifizierten Werte im CW – Modus (Dauerstrichbetrieb) setzen eine geeignete Montagetechnik mit ei nem thermischen Widerstand von Rth< 0.5 K/W voraus. Die zentrale Emissionswellenlänge im Betrieb ist abhängig vom Betriebsmodus: CW – Betrieb (Dauerstrichbetrieb) oder Impuls, Betriebstemperatur, thermischer Widerstand Rth und ist in aller Regel höher als die spezifizierte Impulswellenlänge λpulse (1 μs Pulsbreite bei 4 kHz Wiederholfrequenz). Alle Parameter können im jeweiligen Betriebsmodus von den spezifizierten Kennwerten abweichen. All characteristics and limitations refer to pulsed measurements (1 μs pulse width at 4 kHz repetition rate) on un-mounted laser bars. All specified values in CW - Mode (continuous wave) implies a suitable mounting technology with a thermal resistance of Rth< 0.5 K/W. The operating peak em ission wavelength depends on the operating mode: CW or pulsed, ambient temperature and thermal resistance Rth. The operating peak emission wavelength in general is higher than the specified pulsed peak wavelength λpulse (1 μs pulse width at 4 kHz repetition rate). All characteristics obtained in the operating mode may differ from the characteristics specified herein. 2) Spezifiziert bei der typischen optischen Ausgangsleistung Pop, typ Specified at the typical, optical output power Pop, typ 3) Der spezifizierte Wert für den Konversionswirkungsgrad setzt eine homogene Strominjektion voraus The specified typical efficiency is reached under conditions of homogeneous current injection
