Default SOLD - 2+ Watt 445nm Ultrafire U-501B Beast of a Laser

I just finished another 2+ watt build using this host, so I'm going to let one of them go.

The laser is built in an Ultrafire U-501B, with a massive copper heatsink milled by Flamingpyro and a custom 30 Caliber focus adapter, also machined by Flamingpyro, and uses one of DTR's G2 lenses for the increased power output.

The heatsink alone probably weighs over 1 pound, and the laser feels nice and heavy in your hand. After a full minute powered on the laser just barely feels warm. I'll not go so far to say that it has an unlimited duty cycle, but it is well over a minute.

It consistantly LPM's at over 2050mW on my LaserBee LPM and hit over 2100 on both of DTR's LPM's, so with measurements from 3 different LPM's I will gurantee power on this laser to be at least 2050mW

I will not sell this to anyone that is brand new here and has never owned a high powered laser before, and it is an absolute neccessity that whoever does buy this laser have safety glass!

Sold!

Mark forgot to mention this laser has a custom copper driver heat sink that is it's self sunk to the host body through the pill



This is a very cool laser and well worth the asking price
the heat sink has a clearance to the host body of only .0005" so heat sinking is superb, the best you can buy at any price

and with the driver heat sink this should have a real good run time even at this power out

What driver are you using, and what is it set to? What diode? m140 I assume?

It is using one of RHD's Mosquito drivers set to 1.74mA, and output with a standard Aixiz lense if over 1650mW. To answer the diode question, yes it is an M140 and a pretty effecient one at that.

Well, to be outputting 2watts at 1.74mA, it must be VERY efficient

Dont dig up old threads to ask about sale prices. Prices 2 years ago are VERY different from what they are today.
