40watt green - laserscope

Actually I think you'd have a good chance of doing some damage to the chassis if you had a camera connected to some scanners to keep it targeted/

wel probably only if u where able to keep it focused on a tiny spot and even then 40 watts is not realy a lot when u are trying to burn anything metal
u also would need to focus to beam over a distance of sev hundred meters

i personaly would not be worried when im in a plane and someone on the ground is pointing a 40 watt laser at me (sun glasses anyone ) 8-)
 
Even over a long distance, 40 watts over a 10 cm circle would still heat things up a bit and would at least ablate paintwork and blind anyone who caught it in the eye!

hih yea but wont bring down a plane
but the laserscopes are prety impressive lasers
 
If a 5mW red was enough to delay a helicopter landing I bet this would do a lot more damage.I mean even some reflections would be bright enough to flashblind the pilot.I don't know about damaging the machine itself. :-/ It would be a lot of fun though , using it's destructive capabilities in safer situations.
 
Actually your wrong! :o

As my sig says I have used a 40W laser and apart from blinding the pilot there isn't a lot more you can do...

40W will cut through <5cm of acrylic but only a few mm of metal sheet (like 3mm absolute max if your lucky). + if the dot isn't held perfectly still or is slightly out of focus it will merely make it warm... so a 10cm would do nothing...

I suppose if the plane was painted matt black, the thing were made of a few mm Al (which it is :D) was reasonably close and stationary then yes! you can bring down a plane ;)

Nobody has one yet. This is just info.
And yes, the flash lamp and rod are refrigerated with the same system as in a fridge, using proper freon coolant and all I think.
But hey at that power would it even matter if it was pulsed? I'd just run it 50% power CW rather than 100% pulsed.

problem: you cant CW flash lamps with that kind of power without a power supply the size of a fridge running 3phase...

the nd:yag rod would work fine though

idea: replace the flash lamps with 808nm diode bars 200w of 808 should get same results in green output much easier to drive CW
 
Thing is, 200W of 808 BARS would have an emitting surface about 10cm square.
And have you ever seen a laserscope?? THEY ARE THE SIZE OF A FRIDGE :P
Anyway, the CW flashlamp power doesn't need to be 100% of its pulsed power. Even 10% at liek 400 watts rod output would do.
 
thats why you mount the bars radially around the bar. so you have a radially pumped nd:yag pumping a ktp...
 
I've learnt a lot about laserscopes lately. They operate q-switched for the high power pulses at about 40-50 watts. However they can also run the flashlamp CW at green output of about 4.5 watts.

I'm looking into getting a laserscope KTP and see if I can't make a few nice watts.

But where do you have enough 1064nm to pump it from? :-/

A flashlamp driven Nd:YAG rod. Those KTPs can handle many, many joules.
 
i wonder how it will be like in... lets say... 1,000 years.... LOL think of it... A 100 MW (not mW) portable hand held orange laser... (size of an X-series) for like $5....


ahhh... someday, men will laugh at our "watts"


I myself have not broken 700mW yet, so Im a bit too far away....


regards,

amk
 
the 4.5w seems viable :) flashlamps can run cw at around 10% but not 50%...

still thats a steep price for 4.5w of green i saw one go for $60000 wheras a "normal" 5w green are around $7000
 
That may be a steep price for 4.5 watts of green... But I now got a laserscope KTP in the mail on its way to me for far less than its worth.

Anyone got a decent Nd:YAG laser I could have? I'm looking for a couple joules at least, watercooled if possible with a high repetition rate.

The beauty of it is not in the CW power but the many joules of pulsed power it can manage. A laserscope KTP can handle outputting many many joules of green.
