   Dunno how many people realise just HOW expensive blue laser light was up until the last 48 hours, but if not, it was PROHIBITIVELY expensive!

Very small power ratings could cost you an arm, if not a leg.

However, in the last week a new source of blue (445nm to be precise) wavelength has emerged from an unlikely source and at a phenomenal price.

Casio have released a new projector which is based on LED and laser technology, and comes packed with 24 x 1 Watt 445nm diodes.  As we speak, there are various groups around the world buying these things brand new and instantly tearing the things apart to harvest the laser diodes for use as laser display sources 

To put this into context, last week, if you wanted 1 watt of any blue laser it would cost you somewhere in the region of £3k to £4k.

Today, you can buy all the components to build a module for about £150!!

Expect to see a lot of the cheap crappy ebay Red/Green/Violet projectors dissappear very soon to be replaced by proper (and powerful) RGB's with good modulation characteristics.  The only downside at the moment is that the beam specs are not great, but people are working on lenses to suit these new diodes so it won't be a problem for long I don't think.
