Mitsubishi ML520G71...Red Holy Grail or Flashlight Fail ??

[andyf97]

Super, well done.

got my 3 banger up and running today tested @1.534mw , installed in my projector got everything alighned, fired it up down the hallway
and said to myself ohh f**k.
man what a difference that extra 500mw of red made to my setup, now she bangs 3.9w after optics with 4.5w raw power
need some better dichros to reduce the losses and here's the pics taken in daylight with fogAttachment 31663Attachment 31664Attachment 31665Attachment 31666Attachment 31667

Very nice Chris

i love these 635nm diode but i have to say i still think im going to mix in 500mw of 659nm via pbs cube to help keep some what of a dark red.
Along with 500mw of 405nm to help deepen my 445nm to more of a dark blue.
Also good news diy 1W green lasers can be made for only about 400$ Cant wait for the GB to be over and my projector to be done!

1w diy green lasers for $400 , when did i miss that ??
please do tell more

Well the 400$ is just for the bare needed materials cost and would make you a 1W green.
The selling price would be around 750 to 800$, but these have things like multiple tecs and drivers.
Currently waiting on my PCB's of analog drivers and TEC drivers.
So they are fully plug and play units.
Beam specs are around 3mm by 1.2 mRad. at 29mm height of beam. around 950mw to 1.15W green.

I just finished the latest version of an adjustable X-Y diode position mount with potential application for the G71 LD. See pics and drawing LDADM V7C. The “Outer Limits” Control Voice; “We will control the horizontal. We will control the vertical “ is appropriate here!!

Assuming the performance ( least amount of aberrations) of the ML520G71 benefits to a substantial degree from precise LD positioning relative to the 2.0mm fL Collimation Lens, then this design is ONE way to achieve that goal.

The X-Y location is fine tuned with two (2) M3 x .35 positioners, one for each axis. M3 x .35 has a 76 TPI. The LD Position Disc has movement within a pocket machined in the Component Segment and the disc is spring loaded opposite the positioners. The aspherical Collimation lens is screwed in down beam, at the front of the Component Segment. After the optimal position is determined, the four (4) 4-40 Clamping bolts are tightened to lock down the disc in the X-Y position. That’s it !! Set it and Forget it !!

In my version, the unit is machined from Brass and the Laser Diode Position Disc is machined from Bronze ( 88% Copper). I imagine black anodized Aluminum could be a superior choice for limiting reflections….but…I prefer Brass.

I will use this design in my planned Dual/Quad Red. Looks like Badger 1666 also has adjustable LD mounts in his set up….so….that is a good sign that adjustability is desirable !! Yes… the overall footprint is larger…and the mount cost is more….but the results may greatly outweigh these factors .

I will install the LD shortly and post some additional pics soon. Also…I will experiment with the “ one side pin hole” concept !! Very interesting !! BEAM

Terawatt Labs. At the forefront of future alien technology. Looking cool main. Are you sure that your dog is from this planet?
Seriously, though.. Nice looking work. So, Bronze is 88% copper? Hmmmm .. thermal transferyies-niceyies ... ..

[kiyoukan]

hey cdbeam nice design.
Got my diode de canning tool in along with my 9mm 445nm diode.
Cant wait to have this stuff in my projector.

[steve-o]

Hey Kiyoukan, how's the group-buy going?

[planters]

It seems like there is a lot of discussion about de canning. I thought this was only to analyze the diodes to understand their differences. Am I wrong and there is a movement to run the 445s de canned in projectors?
