Indeed, it's the 6th Edition (Indian release, they had tip-exed that part out though, haha) Look through the index for 'Telescopic Resonator' If it's actually covered at all. Hmm, well, I look forward to trying it out, but first I need a strong ol' laser.

Voice coils are for a separate thing. A voice coil is basically a really simple linear motor. If you apply current in one direction, it applies a linear force in one direction, and if you apply current in the other, a linear force in the other. So, if you pre-load it with some springs, you can...

Aha! You got a point there. Looking over yours, it makes perfect sense. Why would it reflect through the YAG if the mirror is transparent to 532nm... Derp. ... I was wondering about that, imagining losses of the green in the crystal. Well, there we go. I would logically be able to keep the...

Hello, No, my scope doesn't have that, you can see my scope here: https://i.imgur.com/KScAYu6.jpg So the likelihood is that there is nothing in my laser-scope, short of maybe 1 mirror and the Q-Switch possibly, that would be useful in me building a linear cavity? Amazing how far prices have...

Indeed, well you can see my resonator design further up the thread where I've taken a picture of it an drawn out the beams to my knowledge. I have the so called 'bible of solid state lasers' (Solid State Laser Engineering by W Koechner) but a good bit of it goes over my head, though I can...

I am not stupid enough to argue with that. I am stupid enough to ask if I could set up a resonator using the existing parts from the system in a simple YAG assembly (with or without Q-switch) Or would it be a very bad idea to take apart the Z-fold as it holds more value assembled in the way it...

That was just one idea I had been considering, however if it's not quite that easy without major re-cal, I'm not loosing any sleep over it. I had figured that would be the case. I haven't had a chance for assembling a low power system yet, no. But it seems many of the components are easier to...

Ah yes, I came across that thread before too while researching. The main idea is yes, to build something from scratch. I don't know much-if-anything about the Z-Fold set up. I would be wondering if I can save myself some good money using the mirrors from it, I am not certain, but believe to a...

Ya can see on the links I gave, and I mentioned it in the first post, but yes, it's Diode pumped. :san: I don't know how much money more I'd need to be saving for a fiber laser, but realistically, I figure it would be fun to make this into an assembly, a good learning project, and I'm curious...

You are certainly correct. On all accounts. :)

Hello LPF, So, I posted a while ago about a laserscope I purchased (I still have it, sitting at work under a Poly sheet, gathering dust) I realised, redoing a flash-pump controlled YAG system would be extremely expensive and I would need a lot of time to do so, plus a lot of experience. So, I...

I've got a ruby rod here too, it seems in pretty good nic, only a few tiny chips in the edges of the ends. I came across this site, they have quite a lot of parts for Ruby Lasers, including a bucketload of mirrors: Laser Sources Ltd - Ruby laser line optics. 694nm. Output couplers, rear...

Yes, It is nearly / is white when I look at it without my phone's LED light shining at it (just the florescent bulbs above me) I gathered the cavity would need to be completely redesigned. I was already thinking of side pumping. Good motivation for me to get on with my vacuum chamber so I can...

Indeed :p I wonder how many diodes I can pump into that rod... and for that matter, how can I tell what type of doping the YAG rod has.. and how much does it matter to me? (a lot I'm betting from what I have read...)

Ah cool, interesting! I'm beginning to feel my laser is old tech, I'm looking on youtube and seeing these 80W lasers the size of my wallet with a power supply the size of a keyboard... compared to my filing cabinet!
