Product Description

Product Description
Item Name
12W 940nm CW Laser Diode Chip Unmounted Laser Bar Scientific Research 

Features:
Wavelength: 940nm

Output power: 12W

Operation mode: CW
Power Modulation: 100%
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.

Application:

Fiber Laser Pumping Source

Soild-state Laser Pumping Source

Direct Semiconductor Laser
