You can see in my signature what all I have - the only ones not mentioned is a >5mw 532 red pointer, and a very similar 660nm red pointer. Plus, I have another argon laser on the way - this will be a multi-line.
As you can see in my signature, I have 2 lasers at the moment. I RMA:ed the pulsar about a week ago, so the replacement should be here soon. The MXDL is at repair. A 186mw red from IgorT is coming up. Igor also shipped my blu-ray yesteday, so it will be here in a couple of days.
Not counting cat toys, or the six sitting on my desk waiting for me to finish building them, or the modules that have a driver already attached but are not hooked up to a battery, or the one that Muuurph bought last night . . .
I have 25 lasers. Oh wait . . . One of them has three diodes/modules in it. Does that one count as one laser or three?
Don't even get me started on diodes, drivers, or hosts not being utilized right now
