      That sounds pretty handy!
      Do you think you would be able to retrofit your machine with this laser? Does it even fit or is it just a matter of plugging an optic fiber into an input?

      I am pretty happy with the results of my search. I have found at least 4 (150-200mw) 405 nm lasers for prices around 175-200 US. My only concern would be beam diameter but I think I can collimate that to tolerable sizes. I will say that the original beam diameter of  (0.1mm/.2mm) is kinda hard to beat with the retrofitted systems.

      There apparently are single diode lasers in this range, now, at 405nm.
      I think they would cost about $200 from China.
