I have seen thisbin Laserlands store .its semm like laserlands use it in his product "5mw FDA class 510nm laser pointer" .quite interesting .

Diffraction Grating ? ,I have many of them at my school .may be later because -Laser is died ,I will order new one soon -School is on vacation

Oh.So this time like regain memory 😁

Its seem sharp is developing the later version of 520nm green laser diode Link The left side is GH05130B2G and the right side is GH0521DA2G. I cant find any information about this diode ,may be in developing progress. "A comparison between Sharp's new and previous green-light laser diodes. The...

By the way ,I haven't see people around here testing the SLD3232VF ,I got four of them.I will open the thread in violet laser soon .Also If I order the replacement diode,I will make a update here.

Now .I known what to do.so dont be worry .

I hooked up the laser .And I a good news and bad news Good news is The laser fired up successfuly but the Bad news is After I tested with the boost circuit @ around 5 volt ,Laser start to LAZE .but My multi meter is dead -_- so I cant known the current at the time. And the worst news is LASER IS...

This one under is Sharp spec This one under is Osram PLT5 510 I'm comparing with the osram 515nm diode (Sharp 515nm and PLT5 510_B1).

Let me look at datasheet again

Also hope It's can be reach the 100mW

In datasheet said, And datasheet is not mention about the transverse mode ,I hope It's single mode.

Today ,My Laser in arrived .soon (may be 7 pm +7 timezome) I will test the laser and some pictures for LPF.

Ok.Let me find in BST

I had planned to make a LPM (I dont really need the high precision).

Too bad .I dont have LPM or Spectrometer .I can do only two things is taking the photo(s) and testing by adjust current and voltage.

Yesterday I just order the Sharp Green 515nm laser from the LaserLands Store(not the 505nm,Please dont confused.)The model number is "GH05130B2G" amd In datasheet not mention about the tranverse mode... And I found the datasheet on the internet ,Then I mirrored to my onedrive link for further...

Cool built .And thanks for the laser driver link.I targeted on PLT5 510 (10mW push to ~80 mW like in DTR's).

Thanks for advices.I decided to put the diode in the housing with the heatsink(I had this for many xD).

What's about this : https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F232687743588

Oh that's a great deal
