Default Re: Buying: A complete ruby laser head

Yes he sent me some pictures, but these are not pictures of the stuff I will get, but the same kind of laser head and goggles. He says his camera is broken, so I am waiting until he gets some camera to take a photo of my stuff.

Default Re: Buying: A complete ruby laser head

So let me get this right. You need a ruby laser, roughly at 694 nm (reddish light), but you will get instead an Nd:YAG laser (1064 nm) with a KTP crystal? The KTP crystal used in its 1H configuration will give you double the frequency of the 1064 nm wavelength, or, in other words, half the wavelength, so 532 nm. However, do not expect the power to be great, KTP crystals offer maybe 15-25% conversion efficiency, which starting from 3mW won't be too high.

May I ask why you need a ruby laser? Wavelength? You could go with a red DVD diode laser, the wavelength is about 650 nm; or even a HeNe gas laser (632.8 nm).

Power, the strength of pulsed lasers like a Ruby or SSY-1 setup is incredible, usually they can easily punch holes in thin steel. It's more of a novelty item than a real common use one, as they're pulsed incredibly fast, and you're not going to see much more than a cloud of sparks when it hits something. An Nd:Yag setup is used in devices like laserscopes to produce many, many watts of green light. And that's three Mega Watts, which the Kigre Mk.something can do easily, though that's not what he's getting.

Novelty, you say? Trust me, millions are being invested right now into developing alternate etching, texturizing, welding, and scribing with pulsed femto and nano second lasers. It is a very researched field. Soon it will no longer be a "novelty."

Default Re: Buying: A complete ruby laser head

I realize that on a professional scale, fempto and nano second lasers aren't a novelty, but the OP is a hobbyist, therefore this item is a novelty to him. 99% of the people that buy used SSY-1 heads are hobbyists. I'll admit, if I had the money I'd get a ruby setup and a Kigre green setup. Why? Because they're fascinating devices, producing enough light to punch holes in steel, and most people will only use them for stuff like this.

I'm agree... a hobby should not always be something new or something useful
