Hmmm - one serious thought - 'makers' thinking of playing with 1+ watts should also seek out videos of what happens to normal consumer and better non laser grade optics when used as focusing or steering elements - I knew of a lab that basically had very fine powered optical glass blown into the nearby walls (it was empty during the test) - and one less serious thought, from the same lab where I first encountered this sign... "Do not look in the laser with your good eye" :-)
