the mystery dot???

the following video shows my x-65 doing something wierd. its appears to mode hop, but im not sure. i have a lens on it to make the dot nice and big.

That is definately mode hopping mate...

Yeah Timelord is right man. Also I have heard that it is not good to clicky your laser on and off like that so quickly.

I too, saw beam-spot flutter, start-up anomalies, when I first attached a lens on my X25 & DX True 30 and also saw brief bleed through raw-beam power going through my safety goggles.!

I think the pump diode goes through a warm up temp. region. and causes flutter in the normaly perfect phase coherence of beam quality?

I have a experiment for everybody reading this post:
Powerup(fraction of a second on-time) your greanie pointing through your goggles to a white target.(Don't melt your googles,FrothyChimp and others with insanely powefull lasers)

OK; did you see a flash get through the goggles?
Was is because of the light stopping property of destructive interference inside of the filter hampered by the "noisy" beam or otherwise just a LASER powersurge?

MMMMM :

Looking forward to your results/feedback on this.

that was with freshly charged ni-mh batteries. i put in slightly used alkilines had it mode hopped once and did not do it again. :-? :-?

Is it possible your nimh batteries are not performing as they should?

My X105 does that on low batteries. I had some nimh batteries that worked great in them, but slowly they started not putting out as much (lots of mode hopping) and now they are so worn out that I can't light matches with that pair. Maybe your batteries are getting old because I charged my old pair a LOT of times and they are bad now.

styropyro, you might be on to something because now that i think about it, the batteries that i am using are about 3 years old. they have been used and abused ;D
