Hope it's one of those newer "non-carcinogenic tonier" lasers... or you washed your hands soon after =)
Last time I dismantled a laser printer, I found there is an array of laser diodes (one long line of them) along each toner cartridge. SO many TINY gold contacts, SO many TINY bits of glass...
Absolutely tiny, and probably unusable. I had to strain to see the bits with my naked eye. =)

A balloon that explodes, differences in density of the air causes refraction. In the lower left corner you see the microphone that triggered the photograph as the sound from the ballon reaches it.
By using a LED and a candle you can see the effect, I did it a couple of days ago.

Here is the full article which makes interesting reading with the new techniques of a reflective grid and colour filters which allows large areas and outdoor shots.
My favourite amateur Schlieren site and one of my all time favourite but little known sites is Rapp instruments. Site is only in German but he makes beautiful stuff. All my stuff looks like junk compared to his.
Photo is another from that site and shows the muzzle and bullet's shockwave at Mach 2.5 Peter

Well, 60 people have looked at this and only one reply. Keep guessing and I will keep giving photo hints. They were pics I took last night. Here is another in the series. Don't be scared now
