ir laser

[polop]

I have found a laser diod 75W pulsed only roughly 60$  uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6541866 they say they are 75W pulse lasers. ciould these be incorperated into a pionter. maybe they can be ran at .5 W constantly. any ideas

 

[spyrorocks]

Hmmm, I don't really know what to think about it.

75W in a small diode doesn't really happen, but since its pulsed... you could have some fun if it truly has that output.

 

[BlueFusion]

wow, at that price, i'm taking this on as a project!

 

[spyrorocks]

Blue is going to order some, and test them out and see what we can get out of them.

 

[Cyparagon]

It looks like it's meant to be incorporated in a remote control.

 

[Things]

LOL a 75W remote control, blind everyone in the room while watching TV ;D ;D ;D Nice find BTW!

 

[BlueFusion]

Not really cyparagon... this is a whole new beast. Though the average power is only 90 mw, who knows what 75 watt pulse peak can do...

 

[desslok]

Do you think the rating is high because it has 3 emitters? Maybe 25 W per emitter? I would order one for the price, but I don't have a power supply that provides 9V at 40A. Oh well, good luck! Let us know what you find.

oh i didnt think ill get any poitive responce for that effort. i thought everybody would have inside knowlage knowing these wont work. but heeh even a complete noob might stumble on some thing worthy. well at least hopefully caus there is a rs just down the road from me.

a  very short pulse even at high powers wont do much i think, just as the object is starting to heat up it has time to cool down  again.

As regards to a power suply the esiest way would be to use high output batteries. I have some 14.8v ones that can pulse over 60 amp easily and be fine at 45 amp constant. these also are small and light enough to put in a pionter. mmmmm 75W pulse burner.

 

[BlueFusion]

Problem... 40 amps CW into a little plastic diode... NOT GONNA WORK! Its a 100 nanosecond pulse.

100 nanoseconds at 40 amps / 9V is hard.

I have bought two and will experiment to see if they work and are usable. If they are, I'll do a GB for them, as they have nice discounts.

I don't recommend you go and buy any now as they may turn out to be totally useless lol

And I do expect they have 25 watts per emitter.

 

[JECS]

im so anxious to hear the results

 

[spyrorocks]

So am I. I passed blue money for one.

 

[heruursciences]

It's a SH pulsed laser diode, takes amps to run, but only outputs about 4 to 100nS pulses, usually at . 100 ns is pushing it. They are intended to be used in TOF rangefinders. The most common power supply is a capacitor discharged through a fast SCR driven by a fet or UJT relaxation oscillator.

Think I'd rather have a Daedal Phasor! ;D ;D ;D

ok think aboguht buying a 1watt ir for like to use with a fiberoptic cable to do soem fine woodburning what are teh chance of hurting my eyes ( all gogels i fidn for ir are super expensive)

very likely.
