True. I'm more concerned with the fiber/coupling part of the problem than the collecting.
As for excessive power I'm marking wood and leather, not cinder blocks... But there's always something to be said for turning power down.. I have a ex-medical 20 watt co2 laser if i really need to ramp things up, but i really dont think i need much power out of the fiber.
I don't want to use sunlight to save money. If I was penny pinching, I'd use a half watt 405 diode. I want to use sunlight because is satisfying on artistic and spiritual levels for me.

Then again, if your only use is to do burning art, that might be sufficient. I'd still think saving money on the DIY method would be a good idea, but at least work out what your temperature would be before picking a size.
I'd hate the idea of spending Benjamin after shipping, only to wind up hovering over an area longer than you'd prefer.
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
