Hello, I need a laser power meter so that I can measure the laser's optical power characteristics. Something which can read from low as 30 milliwatts (mW) to high as 10 Watts (W). Would like some recommendations on various branded used ones or maybe some new Chinese ones. Not sure which ones...

Hello, I would like to get an idea if I can make an 808nm 3 watt laser myself or is it just better off simply buying one from Odin: Here is their laser 3watt 808nm laser pointer link to get an idea: https://biglasers.com/product/odin-infrared-ir-laser-808nm-980nm-1064nm/ Can anyone explain how...

Hello, I see that a 905nm laser diode is "pulsed" and can give an output wattage of 100 Watts. Wonder if anyone was ever able to drive/modulate/pulse it and can explain how it can be done: Also what kind of laser safety goggles needed...

Hello, What is the most powerful infrared (≥ 800nm) laser diode and also which manufacturer makes them? I'm checking at "civil lasers" website and currently the most powerful Infrared diodes they have are only 1 Watt: https://www.civillaser.com/index.php?main_page=product_info&products_id=161\...

Hello I have some 405nm Sony and Nichia laser diodes ranging from 400mW to 7 W. I want to make some greyscale engravings or markings onto paper using a small desktop CNC using GRBL. Curious if anyone knows how to make a PWM/TTL laser driver circuit, how can I make one? Would be using a micro...

Hello everyone, So I am trying to build a 7 watt NUB44 V2 laser pen. With my calculation in price, it seems this eBay Ad is selling pretty much the same build cost all ready to be bought and build...

Hello guys, 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. Thanks.

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 Thanks.

I want to learn and design custom laser driver boards for pulsing. Will this book help for that?: spiedigitallibrary.org/ebooks/TT/Powering-Laser-Diode-Systems/eISBN-9781510608467/10.1117/3.2268619?SSO=1 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...
