Sorry it's taken I while to get back to you - been in and out of hospital over the last few days/ weeks. I've totally lost track of time!!
My avatar is of the very first laser I got the pleasure of working with. The laser is a Coherent PureLight with the white beam separated out and passed through individual blanking units for colour control. It resembles a game of MouseTrap trying to line it all up and then realign it it every half hour! It's hard work but great fun. The remaining yellow 568nm beam is also visible however the system is complex enough with 3 blanking units on without trying to add a fourth one! :banghead:
There is also a colour wheel built onto the system for the second head output (visible at the top left of the picture).
Here is the bigger version of the picture...
I am hoping to create a bigger album of some the pictures that I have got of from this system.
