anyone knows who manufactures the laser diodes for pioneer 16x blu ray drives? I'm having problems with my BDR-209 405nm diodes, they give a bad beam profile. I want to buy some blu ray diodes but want to avoid at best from buying the actual expensive blu ray drives...
That is true, but with white paper I can see the true beam profile for leaking artifacts.
I'll be using this laser diode for exposing PCB photoresist material. Any hint of leakage of UV light will expose the UV sensitive material.
DTR advertises them to go close to 900mw, but will damage the diode most likely:
So I drove the laser at 5.2 volts and around 220mA, still the same results.
You can't really see the box artifact because the iPhone 6S Plus camera sensor is too sensitive even behind laser googles, but you can still see the artifact around position 5 O'clock and 6 O'clock.
It's really terrible...
So I was finally able to power up the laser diode from DTR.
I got two of these modules.
It is a "900mW 405nm Blu-Ray BDR-209 Laser Diode In Copper Module W/Leads & G-2 Glas Lens":
I have the IC-Haus IC-HKB-S08-TP laser driver chips but for testing purposes of the laser module...
Yes, seems like the Sony's "Sld3237vf" diode is the one used by "BDR-209 405nm Blu Ray Drives".
Here's the datasheet is anyone interested:
I bought the DTR BDR-209 405nm Laser Diode with the G2 Lens from DTR store.
I'm trying to find the datasheet for the BDR-209 405nm Laser Diode.
I'm sure it should have one since it is a quality laser diode.
The reason I ask is because I'm trying to find the beam quality M2 values for it.
So I ended up buying the famous 405nm "BDR-209" laser module with the G2 lens from "DTR" at eBay. Seems like Mr. "DTR" is a serious laser guy, with over 7K 5-stars at eBay, I gotta say thanks to Mr. "Giannis_TDM" and "Alien Laser" for providing such reputable laser source, I always seeks for the...
Wow, this is a solid state module for around $100, not bad...
But it can only outputs about 10mJ of energy... Which could be "doable" for exposing the photoresist, but will require for me to scan the surface for much...
I remember from every other year to year always wanting to buy UV-A (315-400 nm), UV-B (280-315 nm) or UV-C (100-280 nm) lasers, but there's no such technology available in the market as of now.
Where did you see a gas UV laser shorter than 405nm? I just went on eBay and couldn't find any...
I think it would be better to use a laser with a shorter wavelength such as 300-355nm, the G2 lens will cause the laser beam to be much shorter focal point than using a 405nm laser. But not sure how much of a difference it would make...
Wow, interesting... here's a quote:
"Compared with CD/DVD laser, the Blu-ray 405 nm laser has a focal point of approximately 250 nm, thus being suitable for...
