Well, in fact there isnt anything that 'stops' you from doubling it again, though i doubt that there are crystals that can handle doubling the pump wavelength AND the doubled result. 266 nm lasers are, however, made by doubling 1064 to 532, and doubling again to get 266.

Similarly, 1064 is tripled to 355 nm. This is commonly done by first generating 532 and combining that with the original 1064 (which is possible since they are exact doubles), although it is possible to triple directly to 355 using intracavity non linear optics as well.

If you think that would work, then what would stop those 404nm from being doubled AGAIN inside the crystal and make 202nm, in it's turn into 101nm, and so on till you get frickin gamma rays?? :eek:

Just a silly theory but you get the idea. :crackup:

In my mind, that couldn't ever work, because the crystals are only designed to modify 'light', not gamma rays (or radio waves for that matter...if they were, you could turn an FM transmitter into a laser with a few crystals.

Seems like you missed the point...

and when you can get half a watt from a diode

I know this is a bit late (I just saw it) but I don't know of any 405nm diode that is good for 500mW for any respectable length of time, if it would even survive the initial start up, because Dave got lucky with his 500mW 8x, and even with the 405-G-1, <400mw is a loooongshot. Just my $0.02.

Thats how long he tried before finally figuring out it wasnt going to happen, period ;)

And it really IS a pity it is not possible to double diode output just like that, otherwise we'd have a range of doubled lasers covering the entire visible spectrum (as IR diodes between 800 and 1600 are easily produced).

Even if it could double x rays, gamma rays are <10pm (.01nm) It would need to be doubled:

10 × 2^x = 405,000

Sixteen times. With the inherent losses in the processes, you'd be left with nothing long before you ever doubled it 16 times.
