Default Homemade Labby 200mW+

I housed one of my Lanling modules today in an old WL laser case ;D ;D. I cranked up the onboard pot to max output , put a 5K ohm pot in series to give 0-200mW+ output and added TEC cooling to my homemade heatsink.

This module was laserchecked several times before the mod and was outputting a steady 197mW. Cranking up the pot on the driver board has made it noticeably brighter, so i can only guess the true output is way above 200mW. The diode is drawing 2.96v and holding at a steady 300ma of current. The underside of the heatsink is TEC cooled , however I doubt this is really necessary, as the heatsink is so big , it does not even get warm.

This is a beast, it does not just melt black tape, it punches straight through it and will cut a strip in less than 5 seconds, matches are instant. I dont know how long the diode will last at this power but the current drain is constant (tested over 1 hour constant on).

Great new toy ;D ;D

Nicely done. Labbys are awesome...I got my DIY working again with a TEC and it is drawing 420ma's...but it is an open can diode. I can burn through a floppy in about 10 seconds...lol I have some improvements I need to make...never ending fun.

But it's like I try to tell everyone, there is more than burning. The beam itself is awesome...and I know everyone whom experiences a decent power laser for the first time will be in awe..

Very Impressive!
I hope to at least come close at my attempt.
I do have issues with overpowering all my LD's though. I'm still in denial yet.
Maybe I should start OverPowering LD's Anonymous?

It does look really good, eh?

I love it! Although... from the picture... I would say it's about ISO-100 and some smoke in the beam

200mW needs a looong exposure to show up clearly like that, but that picture is really nice
