I came accross this and wondered if anyone has tried it with a "C" mount? Not sure if it would work with a can laser. Marconi> what do ya think?

Yes, I have done it with C mounts for DPSS lasers.
Cans with windows is much harder.

I like this bit.....
does that mean you can post it on our forum

If you need to ask the question 'whats so good about a laser' - you won't understand the answer.

They most likley have a longer cavity length and therefor, more light output in the same emitter stripe.
CLICKY!!!

Not sure about that one. From what I have seen, Maxyz have (as usual with DI diodes) a fairly elliptical beam. The microlensed diodes I have looked at have been circularised - and lower powered than their non-microlensed counterparts as a result.
I still want to know how only one person can find these special higher powered diodes, and they don't seem to cost mega-bucks
Which was always my contention anyway. Though it's not the quantity that matters so much, many of that width put out more. What's important is the extra length might make it much easier to tame the beam. If anyone's got a dead one and wants to do some foraging, see if you can find some non-round microlenses in there... You might need a microscope to see them if they are.
Ok, was just a thought. Like I said in answer to Ben, I'd always thought it was just a longer cavity before this new wheeze occurred to me. I'm not sure if all microlensing will get a circular beam anyway. To do that you need very precise positioning. Maybe all we want to do is tame the fast axis a bit so it is no more eliptical than an unlensed single mode diode. (Most DVD diodes actually ARE microlensed, I was told recently, I think by Steve Roberts or Sam Goldwasser). In this case it might be a lot more efficient. The idea is not to circularise the beam perfectly, it's just to make sure we lose less light by optics loss, than we otherwise would by blatant spill, while at same time getting a shape that makes a narrow beam with little divergence possible with a single asphere. A single cylindrical plano convex lens might do it, if it is tiny, placed right up close to the diode chip inside a can.
Yep, the bottom line is that one, that's a deeply technical issue I really want to understand.
