[quote author=VW link=1211245147/0#13 date=1211314875]It's quite a coincidence because when I first recieved my SBP40, it decided to mode hop into two beams also. It's happened a few times, but I can't say I've noticed any other mode hopping that ruins it. But yeah, like you after leaving it to settle again it sorted it's self out. I think it might just need breaking in after the shipping and all, because it happens so little now on the Spartan I don't think it even mode hops at all.
Is it possible to damage the crystals from over heating them with the diode? [/quote]
You are right, I'm pretty sure it doesn't matter whether it's constant wave (RPLB) or pulsed (SBP), the optical equipment will always be very sensetive to temperature. With the Spartan, it sometimes takes a second or two to brighten up if it's cold, and when it does happen, it's never in the 20's which is optimum temperature for the laser to run. But when it's warmed up (after use or increase in temperature) it works perfectly from the click of the button, I just want it to get a bit further into the summer so I can get some decent heat as it's never broke 18 so far and it obviously drops loads at night too.
