Default Epic LPM Graph...



I love how the output goes up as the laser "Warms up"

New record for a mitsu 500?

Normally the output of the 500mW Mits diode goes down when the temperature rises.
The peak is just after the start and not after 4 minutes.
But the output is impressive. What was the current ?

The build has a TEC, so the diode actually gets cooler as time passes
Diode is running at 1.5A

We use a large adjustable current TEC on our 40Watt FAP Laser
and you can easily see the power go up when the cooling is
engaged.

Seems like the TEC does what you expected... Well done..

"Warming up" while being TEC cooled. Clever.

Oooh pretty damn good performance!
That's a keeper for sure, I am also thinking of
building a lab style one with TEC for some crazy

Ya with a lab style you can get even more fancy and add a fan,
but what these diodes really needs are some correction optics

@Jerry - What is FAP laser?
It is a fiber coupled Laser similar to these....

Coherent High Power Diode Laser Module FAP800 50W 808 5nm | eBay

BTW I wouldn't buy that one because the LD pins
are not shorted and bent..

Coherent Inc. Fiber Array Packages (FAP?) 800 Series diode lasers.

This is the LD Module that is inside the unit above.
