I was reading this first article about how IMAX will be using some laser bases projectors, and in one of the links in the article I notice a few potentially interesting technical aspects about a laser light source. As a note, the second link about the laser sources may not be the same one that IMAX will be using.

IMAX to start laser projector roll-out



Laser projectors promise brighter 3D experience (published on 02 November 2010) Potentially outdated:D

"Laser Light Engines (LLE) ... alternative is a light engine producing red, green and blue primaries from the same laser source"


"Our design is a diode-pumped, solid-state laser system using very mature, low-cost GaAs pump diode bars, MOPA architecture, and non-linear optics for wavelength conversion," commented Beck. "It satisfies all the key requirements: power for 3D brightness, a long lifetime, and high wall-plug efficiency for decreased operating costs. The beam also has a low etendue, which is beneficial for fiber delivery and for scaling the power to higher levels."


"Our strategy is to provide RGB engines in increments of 30,000 white balanced lumens," said Beck. "These will initially be aggregated, so as to supply projectors with input powers of up to 60-90,000 lm. In terms of watts, these modules would output 75-90 watts of RGB."

I think by "MOPA architecture" they mean, Master Oscillator Power Amplifier (MOPA)


If they ever drop down to a reasonable price maybe DTR can buy one for the diodes:crackup::crackup::crackup::crackup: LOL!
