This is not a used laser. It is assembled with all NEW components and has been used only for testing and beam-shots.
Features:
Specs:
Details:
I chose the best components available for this laser for the best balance of power and stability in a compact form.
The asterisk * after the duty cycle spec is there because I want to make it clear that these high power blue diodes make a lot of heat. That is unavoidable.
Considering the small size of this host, there is not a lot of mass to collect heat. The laser is intended to be used as a momentary on-off laser and performance will be best if it is not used for extended periods at a time.
However, the advantage of using a small host with little mass is that it cools off quickly. I will recommend a short duty cycle just to be conservative. If you ask me, this is the limit for a host this size. Any more power and heat and power constraints will have an effect on performance.
That said, this laser packs a lot of power for its size. It is built to be a robust "EDC" (every day carry) laser pointer for pointing out stars, showing off to friends, or whatever you like to use lasers for.
SOLD.
And here are the pics and videos:
