Another lazy CNI head. Got one of those B&W TEK lab heads from nkgamer. nice head. but it wasn't TEM00. It started out as TEM 01 and then a skewed ovular TEM00 with two ovals above and below that didn't belong, so almost TEM02. it was output stable... but the mode was utter crap. realigned it and it's happily lasing at a round TEM00 now, and still its normal stable output with no power loss.
Pic of the inside: note the absence of 473 going back through the cavity. I cleaned it up so as much of the light was going through as possible with minimal losses.
More 473nm goodness!
Round output! no funny biz going on here!
