Features

 Efficient radiation source for cw and pulsed operation  Reliable InGa(Al)As strained layer quantum-well structure  New optimized single quantum-well structure  Improved reliability, low treshold current, higher efficiency  Small TO-220 package with efficient thermal coupling  Included thermistor allows wavelength control by temperature  Laser aperture 200 µm  Cylindrical lens for correction of the vertical axis

Applications

 Pumping of solid state lasers (Nd: YAG, Yb: YAG, …)  Medical and dental applications  Soldering, heating, illumination  Free space data transmission  Energy transmission  Testing and measuring 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”.

Alle Laser werden vorgetestet und gemäß den gemessenen Kennwerten ausgeliefert. Bezüglich Sicherheit, Verpackung, Behandlung, Montage und Betriebsbedingungen lesen Sie bitte sorgfältig unsere „Notes for Operation I“. Mechanische Montage Befestigungsloch (geeignet für M 2.5). Durch die gute Wäremeleitfähigkeit der TO-220 Bodenplatte (Kupfer) wird die Wärme auch bei Befestigung an nur einer Seite gut abgeleitet. Zur exakten Positionierung des Gehäuses und anderer Teile, z.B. Linsen, kann das TO-220-Gehäuse mit entsprechenden Klemmen oder Schrauben (max. M 2.5) befestigt werden. All devices are pretested and will be delivered including measured laser characteristics. For safety, unpacking, handling, mounting, and operating issues, please read carefully our “Notes for Operation I”. Mechanical Attachment Mounting hole (suitable for M 2.5) Because of the good thermal conductivity of the TO 220 base plate (copper) the heat loss is properly dissipated even if the component is attached on one side only. For exact positioning of the TO component and other parts, e.g. lenses, the TO 220 package can be attached with appropriate clamping devices or screws (max. M 2.5).
