Slow Axis (H) Divergence: 10 deg typ
Fast Axis (V) Divergence: 40 deg typ (<1 degree with FAC)
Maximum current: 28A
Typical forward voltage: 1.8V
All laser diodes need to be powered with a current regulated laser diode driver. These units need a driver that can source up to 30A with a compliance voltage around 2V. A voltage regulated power supply is not suitable and will damage or destroy the diode. We individually test test all of these with an LDI-830 benchtop laser diode driver and a water cooled test fixture.  We've also seen good results using Lumina Power LDD-100 and LDD-150 drivers which turn up on eBay from time to time.
These require adequate heat sinking to avoid overheating.  For longest lifetime, the diode temperature should be kept below 35C (95F). Water cooling or a large heatsink with a fan will work to prevent overheating. However, a temperature controlled baseplate, typically using 1 or more thermoelectric coolers (TEC) is preferred.
The output from these is a wide stripe of individual emitters. It is not practical to focus the multiple beams to a small spot for marking or engraving. The output is infrared and nearly invisible, but is still quite dangerous.  It is critical that you wear laser safety goggles rated as least OD3 while working with these diodes.
Note that these, like all the electrical components we sell, are listed with no returns allowed.  They are carefully tested and shipped in anti-static materials so we know they will arrive in good working condition.  Laser diodes can be damaged by static electricity, reverse polarity, over-temperature, over-current, none of which is detectable without fully re-testing the unit.  We
will
accept returns for laser diodes which are
still in our original, sealed packaging
.  Once electrical components are opened, we can't accept returns.
