New single mode 520nm diode from Sharp

[Singlemode Laser]

Hi all,

just found this and want to share it with you:

https://www.reddit.com/r/MVIS/comments/8rkboa/sharp_increases_green_laser_output_4x_targets_ai/

It is the 520nm diode that was on Sharps website for ages, and marked as "under development". It will output 130mW (this is the spec from the datasheet), but we all know that these can be driven at multiple of this rating :wave:

Here is a picture with the new and the "old" 515nm diode:

Can't wait to see the first beam shots here in the forum!

Thanks for the share. Fitting that a member with the name "Singlemode Laser" would share a new singlemode diode

Not as unique as the cheap cyan diodes that recently came out, but it's still nice to have a new diode.

I am only interested in single mode diodes :drool:

Thanks for the link, Singlemode. I am always interested in new laser diodes. Though this is not a new wavelength, it is new from Sharp.

Thanx for the news ! This LD will warrant a new EDC build. :drool: Hmmm....No " Quincy Magoo " corrective optics...therefore....small !!! Likely drive to 200~250 mW ???

Any link to info ?? Jordan....add another one to the stable ???

Thanx again

Oooh that's good to see they finally got 520 figured out. That might mean their 3-in-one RGB diodes are next in line.

Here is some mention of Sharp RGB modules >>

What have I got to lose by asking
Is this Sharps 130mw rating which can be pushed much much much higher like we usually do with all diodes ?

 

[deadshadow]

well those are good news as all of the low powered single mode sharp diodes that we had till now could safely pushed up to 2 or even 3 times above the rated power. who wouldn't like a great single mode 300mw 520nm laser?

Interesting news about a Sharp RGB diode. Is there any new information about the ones made by Sumitomo ? IIRC it was extremely hard to find any affordable drivers. Thanks and Please Take Care.

I'm hoping that we will be able to buy these at a discount for quantities. I would love to have a ~520nm single mode laser at 300 mW, but that remains to be seen at this point. Could PBS cube combine two for about half a watt of decent divergence.
