Output power (W)





Overview of JDL-BAB-20-19-940-TE-80-2.0:

The JDL-BAB-20-19-940-TE-80-2.0 is a high-power, 940nm, unmounted diode laser bar, with 80W of CW output power, designed for the most demanding applications.  They are extremely reliable, efficient, and durable.

Our semiconductor products are easily assembled using standard soldering methods. The material supports both soft solder (indium) and hard solder (gold/tin). We deliver our laser bars to you with emitter structures separated on the p-side as standard. On request, we can also produce bars with continuous p-side metallization and adapted facet coatings, using low AR coatings for the assembly of external resonators.
