60 Watt Coherent Laser Diode Test

This is a test of a Coherent laser diode array module. Although small, this laser duode module is capable of producing up to 60 watts of 808nm infared light. This is enough power to be able to cut paper, cardboard, wood glass or even steel! The laser runs on only 2.5 volts but requires a lot of current to be able to generate that kind of output. The laser also requires water cooing at a stabilized temperature to create peak output power and keep the laser diode from burning up.

I'm eventually planning on using this laser as a pump source for a YAG and frequency doubling the output of the YAG with a KTP to achieve around 10-30W of 532nm green.

Please feel free to post a comment if you have any questions.
Enjoy!

2 Questions:

-Is 60 Watt the total power consumption of the laser, or only the output power (power of the laser beam) (80A*2.5V=200W)

-Isn't it dangerous to look at the point where the laser hits its target, even if you cant see the light?

Thank you and nice vid!

@ThePizzahero1 60W is the max optical output power. The rest is dumped via inefficiencies as waste heat. Thus the reason for the chiller.

Yes, it is very dangerous to look at the diffused radiance as your eye will not feel the pain until damage is being done. I wear goggles when dealing with powers at this wavelength.

You need to offset the angle of the lens you have on the end there just a few degrees so that reflections from the first surface of the lens dont enter the diode module and damage the sensitive emission surface.

[hightechstuff2]

@nucleochemist It's AR coated for IR and the other corrective optics in the head would absorb the last 1% of the reflection.

Where can I find stuff for make it ??

[hightechstuff2]

@nikocecca ebay and industrial surplus.

[hightechstuff2]

@zRev1983 You're right... you are not an electrical engineer. If you were, you'd know that power conversion is never 100% efficient, hence the need for the large chiller to dissipate all the waste heat. You might want to think again before you try and give advice.

@85Damix Yes, badly.... It melts brick so.... yeah.

[DriftingTaco]

At first I thought the brick looked like solid rocket fuel and I was like "bitch u crazy" but them I was like ooooooohhhhhhh

It's not ironic I am drinking a Milwaukees best ice right now, Death ray. Very cool video!

[NerdMirage]

I have a large unit too

[ba3cool]

@hightechstuff2 Mind me asking where you picked up those safety goggles, and their OD rating?

[cannabudsguru]

cardboard goes poof

[thatoneguy99100]

you should get two more and make a huge DPSS white laser with 532 and 473 nm YAG and corrisponding mirrors... then you could just use a high power visible red laser and you'd be set!! either way, awesome vid!!! and a 532nm yag with this as the pump would be awesome! maybe q switched?

I would have appreciated to see a soda can cut in half or something. :-(

imagen what the army can do.

I thought brick was gona be in two.
