Hey,
I'll take the risk to sound commercial here. I am from cascade technologies, a company dedicated to develop commercial applications around the integration of QC lasers.
We have developped scientif instrumentation to pulse and drive QC lasers, should you be interested, please visit http://www.ctscientific.com
As far as a cellphone size instrument is concerned, this is to happen within a few years, but there's still a lot of work to be done. Please also check the competition (daylight solutions, Laser components, neoplas...sorry for the other I forgot to mention), they are developping similar instruments based on different aprroaches.
I hope this will help.
