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...

Hi All, I am working on a speed finder project and bought Excelitas Technologies TPGAD1S09H. Attached is the data sheet...

Your microcontroller can't deliver the current needed to drive a MOSFET gate at high frequency. There are MOSFET driver chips available. Some of these are rated for several amps of drive current and might eliminate the need for the discrete MOSFET altogether.

...Total radiation: 60-90 mW Laser radiation: 0.4-6.25 mW Infrared radiation: 30-90 mW . Red LEDs: 2-10 mW Wavelength of: Laser radiation: 905nm Infrared radiation: 875 nm Red radiation: 635 nm . Laser beam parameters: The product contains a class 3B near IR laser having following beam...

Here's the ebay seller I bought a lot of those V400 laser rangefinders from, he usually has a lot more than he lists and the price can come down for large quantity. https://www.ebay.com/itm/Laser-Rangefinder-SELLING-FOR-PARTS-Class-1-Laser-Power-75W-905nm/163276176993

...or invisible laser,if you want a visible laser,max power is 8W one each NUBM44-V2,dual is 15W but if you want a invisible,you have many options, a CO2 laser,a IR 905nm or a Fibel laser(power can reach 100W or more) about goggles,yes,you need it buy a good glass when using a high-powered laser

Ah, I was unaware people posted it on the forums before. I guess there are no obvious hobbyist uses for it.

This has been discussed dozens of times prior: https://laserpointerforums.com/search/177534/?q=905nm&t=post&o=date Average power is maybe 10-30mW (if memory serves) which makes they all-but-useless for anything any of us dabble with. Don't confuse power with energy. This is a very low energy...

...I believe the diode in the V400 (link) rangefinders I bought use this 75W radial packaged model: https://www.ebay.com/itm/SPL-PL90-3-OSRAM-New-905nm-Infrared-IR-Laser-Diode-75W-Pulsed-Laser-Tube/222350512736 Also, not cheap, but here is a link to some pulse laser diode drivers...

Yes, you read that correctly. 90 watts. Get it tomorrow for $23: https://www.arrow.com/en/products/splpl90-3/osram-opto-semiconductors It seems that these diodes are used for lidar and rangefinding. Any ideas what else they could be used for? Any crystals that can be pumped with this? The...

...with High and Low levels (digitalWrite of arduino), but I have problems to increase the frequency to which I want the led to work (infrared of 905nm). When the pulse width is 1msg, it almost no longer emits and at that point it goes off. I have tested with these three FETs (IRF530, IRF520N...

...MD or Podiatrist and discuss the issues you have. Google "laser nail fungus" over 3 million listing come up. There are dozens of sellers of 905nm laser devices sold on eBay and Amazon from $74 to several hundred $s for home use and several thousand for professional use for the purpose...

Low divergence such as with single mode diodes and DPSS are much better for long distance visibility, but I know that you know that. Is the 905nm diode you have a single mode ? Interesting how those rangefinders pick the scattered reflections of the pulse train out of all the background trash...

...of broken/for parts laser rangefinders listed on ebay: https://www.ebay.com/itm/Laser-Rangefinder-SELLING-FOR-PARTS-Class-1-Laser-Power-75W-905nm-/162719994146 - If you buy a few, as I did, the price can be much better, make an offer. Maybe he will take $10 ea for a couple or more, I don't...

hello everyone today i came to a weird find on ebay.this is supposed to be a 905nm 4w pulsed diode in 5.6mm package. :eek: another thing that i saw is that on the title says 'A series' and if you read the description it mentions this: Beam Quality: - A series mean that the chip will produce a...

...and skills to be make one. MUCH more power??---the same guy did a 200W version see link below. To do anything like that in invisible 905nm with no knowledge or experience is beyond irresponsible, reckless, crazy, dangerous to you and any other people around you and very expensive. Seriously...

...For starters, those "70W" diodes you're talking about are nowhere near as powerful as even one of the diodes used in Styro's laser shotgun. The 905nm diodes are 70W PEAK, they are pulsed, each pulse is going to be on the order of 1ns-100ns with a duty cycle of 0.1%. The average power from...

...of "laser bar array? Can you provide any real world actual example of it? If you can not even articulate what you want to do that you imagine 905nm laser diodes are the answer for---how can anyone help you? You have turned it into a meaningless overly generalized question about nothing in...

Exactly Diachi. Is beginning to sound like a daydreaming troll or someone with no clue about lasers or what he is doing or wants to do wasting everyone's time with meaningless daydreaming rubbish. Either give us actual real world details --everything is possible in imagination, not so in the...

...Schematics? More details about your intended application? The diode in your first picture looks like one of those high peak powered pulsed 905nm diodes used for LIDAR. That form factor is not capable of 70W continuous. The picture in your second link is a NUBM05 array, a 30W 455nm CW...
