bang goes the theory – a homemade laser

We’ve just studied stimulated emission and how it can be used to make a laser.  I noticed the BBC1 schedule for this week says that Jem is going to make his own laser in this week’s programme.  BBC1 Scotland will show the programme on Friday 15th April at 20.30.

You should be able to watch it online before then – look for episode 5 of series 4 on iPlayer.  Here is the trailer.
