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

[andythemechanic]

Hi Lanek,

this seems to be the most asked question to this modules, in lasefreak as well.
I have mine from Phillip, from live-lasersystems.at (his name on the forum here is phritzler but he doesn't post very often.

yes, i know this fine gentleman. thanks!

Ha! Great lyrics CDB, when does your album come out?

Just thought i would post the dual diode build design i am making
Kiyoukan's compact dual diode setup
114mm long, 45mm tall, 66mm wide.
(Some dont know it but I am a 3D designer)
Attachment 31182 Attachment 31183 Attachment 31184 Attachment 31185 Attachment 31186
Lens holder made by 3d reprap printer.
Will be selling lens holders once testing is done.
Drop in the holes and add tiny dap of glue to the side and done.

Neat looking visuals

I need some basic numbers tabulated for this diode. A few of them may be distributed through the thread. Some may need to be obtained if any one has the equipment.
1. Beam parameters after the 2mm lens;
Near-field
Far-field
Deviation X an Y
2. Wavelength and wavelength variation. The data sheet specifies 10 nm. Is this just to cover their ass or are several nm variations typical?
3. Line-width

Had another thought. I know I am risking the dead cat thing, but has anyone looked at using the inherently large divergence of the short FL collimator lens to eliminate the first negative cylinder. Just place a closely coupled +/_ cylinder lens pair as an adjustable and very week positive net cylinder to cancel the divergence at the point where the beam reaches an acceptable size, as in 2-4mmx 4mm?

[LaNeK779]

i have gotten a beam out of this setup you describe, but the results with a cyl pair were better

i will check again as soon as i have more patience

[kiyoukan]

Well i am ordering 2 custom lenses to make the first diode lens not needed.
Were going to see how it goes.

This is going to be the longest thread in history.
