500mw yellow laser HOW?

500mw yellow CW.
At 1% efficiency you would need 50,000mw of IR to power that I don't even want to know the price.

Yikes!

That's the company FrothyChimp works for... maybe he can provide a few more deets? :-?

500mW of yellow would be awesome though...

Yeah, don't even ask the price. Look at the price of the 200mW and you can guess what the 500mw goes for. The laser heads are tanks, massive chunks of metal and TEC/Fan systems cooling the pump diodes.

50W pump diodes are nothing when you get into real research and industrial laser systems. You can even buy them on eBay. The 60W 532nm system we offer uses 300W total diode bars to pump an Nd:YAG rod.

At what price though?

Surely then you could get 100mW with 10W of IR, it would be one beefy system but price wise, would actually be that bad concidering...

It's about $1 per mW that the diode pumps out. I honestly don't know what would be cooler, 500mW of yellow, or 50 MEGAWATTS of IR. Seriously, just think what you could vaporize with that (Including your $60 safety goggles )

Wow!

I like how a laser that weighs 40 lbs can be described as "Ultra Compact"
Or that one that likely costs well over $20k can be described as "Low Cost"

All things are relative. There are people out there who would look at this and think, "What a steal!"

That's because we don't sell to you. 20K is a drop in the bucket for researchers. If you can lift it, and it doesn't require umbilicals to cooling systems or has a low footprint it's compact.

Say these words with me (with the reverence they deserve) (Music in the background helps too)

Government grant

Military research

Endowment

Philanthropic trust

Breathe in the rarefied air.

Now get back to work!

What would you use a yellow laser for that other colors cant be used for? Besides the awesome factor...

What kind of research would you need a 500mw yellow for? I can understand the need for UV lasers in research. The yellow might be more useful for a sweet laser show if you have briefcases of cash lying around.

who knows, argon lasers can be used in DNA research, so there may be an application

Most of the time in biological sciences the wavelength is selected based on the fluorescence of the dyes and markers used. Yellow is very popular in physics for adaptive optic telescopy where the cost of a sodium laser is astronomical.

I have a client now looking at a 10W 532nm CW system for a 120 mile communications test. No one would ever use a 532nm laser for communications but for the proof of concept it's all they need. Once complete I'm sure the laser will find itself sent to the back storage room or destroyed based on the terms of the grant.

The researchers I deal with are working on basic research meaning that they are not engineers. They are not building full scale operational systems. They are testing and modeling concepts that may someday be used in engineering using a different technology.

Please keep in mind that the pretty colors of a laser are a hobbyists myopic view. The color means nothing to the researcher. They need a specific wavelength and that is what they order because their research design requires it, not because of the pretty color.

How many of you use thermally stabilized 785nm laser systems? None right? Well they fly off the shelves for scientists requiring Raman spectroscopy. The needs of scientists are far from the needs of a hobbyist. The use of lasers in basic research and applied research is so common that no one can name all the uses. I try to ask, if given the opportunity, what the systems my customers purchase will be used for and I am totally amazed where they end up.

In my business it's not about the pretty color. If you want that see wicked lasers.

OK Frothy -- We want that in a pen powered by 2 aaa cells.

Get on it for a GB ;D

Yeah, yeah, and you want it cheap right? I can hear it now, "Well since yellow is between green and IR, and with IR so cheap and green a bit more pricey, the price of the yellow should be between the cost of green and the cost of IR."

I think I might buy one or two to pop some green balloons I have laying around... my DX30 can't pop green balloons, so I have all these extras laying around I'd rather not let go to waste..
Do you think this would pop them or would I need to take the crystals out? ;D
