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...
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.
I can't find any information on the internet for such basic task.
What are the proper steps, procedure, tools, optics and materials needed to focus a 405nm laser close to 0.01mm (tolerance +/-0.01mm) all day long?
It's going to be this laser module:
NEJE 405nm 3500mW Laser Module
I want to learn and design custom laser driver boards for pulsing.
Will this book help for that?:
It seems this book is only good for continuous wave powering, I don't see any of the table...
Alright I'm designing a laser scanning device that uses a polygon mirror motor found in laser printers.
The laser beam must always be in focus to get the highest resolution scans, therefore all laser printers uses a "F-Theta" lens so that the laser beam
focal point will always be in focus for...
