Has anyone tried to use a laser as a DLP light source?

Hi guys,

I'm looking for information about alternative light sources for a DLP projector.
Specifically, I'd like to use a diode laser as a source.

I'm thinking of a beam expander to fill the DLP chip with collimated laser light.

Any thoughts/links to similar projects? I appreciate that the output would be vey limited. The projected image size will be no mor than 10" diagonally.

Thanks

Doug
