The Laser Trend

LLE then publicized an industry effort to shift the regulatory basis for lasers in cinemas. Sony has announced participation with that effort, though they haven’t made any further announcements since their 2008 technology release (or the recent rumor that they are working with a French group on a cinema-based laser project.) And now NATO, the US-centric national association of theater owners, is forming a laser task force 

Here are a few paragraphs of the Optics.com article. Er note that the anti-green speckle effort that is mentioned in the article takes on significance when reports come back from Rochester indicating that they haven’t completely handled the problem yet.

Optics.org – Laser projectors promise brighter 3D experience – Excerpts:

“Xenon lamps have reached their practical limit for high-brightness applications,” said Bill Beck, a co-founder of LLE. “High-lumen projection tops out at about 30,000 lumens with an 8 kW power supply. Most of the size, weight and power consumption of these projectors is driven by the illumination system and supporting optics, which is why they are very big.”

Laser alternative
LLE’s alternative is a light engine producing red, green and blue primaries from the same laser source, with the output coupled to a digital projector using optical fiber. With virtually all the laser power successfully reaching the projector chips, the result is a system that can deliver two- to five-times the brightness level of a xenon lamp.

“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.”

The company says that it can scale up the power of its system by aggregating the output from several light engines. “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.” The company envisages these multiple RGB engines being delivered to a digital projector by optical fiber, potentially 50 feet away, allowing “a very small box to become a very bright box.”

Speckle secret
LLE also says it has cracked one of the field’s particular headaches: green speckle. When a highly coherent light source is used for projection displays, viewers can sometimes perceive an interference pattern as an image artifact, although the severity of this problem can be very subjective. It just so happens that the green channel is the hardest to acceptably ‘de-speckle’, because of the eye’s high sensitivity to those wavelengths.

Beck is keeping the secret of LLE’s victory over green speckle to himself, but admits that it was not an easy fight. “Dealing with speckle was one of the key challenges, up there alongside the development of a low-cost middle-volume manufacturing platform. We have worked for three years to eliminate the speckle, and have existing and pending IP in this area. All I can tell you is that it is really, really hard and lots of people have tried.”

The LLE light engine is also green in spirit, contributing to the energy savings that the cinema industry expects to make as digital projection systems become more widely adopted. LLE predicts that RGB laser illumination will reduce operating costs for movie theater owners by potentially $10,000 per screen per year, by eliminating the need to replace expensive xenon arc lamp projector bulbs and reducing electricity use by as much as 50 per cent. As Beck noted: “Our business model is very much in line with the trend to replace low-efficiency lamps with solid-state solutions, offsetting higher up-front price with lower total cost of ownership.”

“Doug’s experience developing the Digital Cinema market is unparalleled,” said Jiong Ma, principal, Braemar Energy Ventures, and director of Laser Light Engines. “His leadership will be invaluable to the continued progress of Laser Light Engines.”

Mr. Darrow succeeds Bill Beck, Laser Light Engines’ co-founder, who will remain active in the company as executive vice president, business development. “We started Laser Light Engines two years ago to bring the benefits of high brightness, energy efficient solid-state laser illumination to Digital Cinema and other large scale projection applications. Having demonstrated our technology, it is now time to drive commercialization and widespread adoption,” said Mr. Beck. “We are all very pleased to have one of the most experienced players in the industry to lead the next phase of the company’s growth.”

Laser Light Engines combines advanced laser technology with high volume manufacturing processes to provide high brightness, energy efficient, long lifetime, color-controllable light sources for demanding illumination applications worldwide. The company is developing solid-state light sources for 2D and 3D Digital Cinema and other large venue projectors. Laser Light Engines will produce light sources that have three to five times the brightness, 100 times the life and half the power consumption of arc lamps, the incumbent technology. The company will manufacture a light source module that can be incorporated into a standard Digital Cinema or advertising projection system.

“I am very excited to be joining the Laser Light Engines team and look forward to bringing high brightness laser engines into the market,” said Mr. Darrow. “These innovative solutions have many advantages that promise to revolutionize large screen applications.”

Prior to joining Laser Light Engines, Mr. Darrow spent twenty-three years with Texas Instruments. His most recent role was in the DLP Cinema® Products Division where he led all marketing for the division, as well as its effort to develop break-though solutions for Digital Cinema. He played a key role in changing the entertainment industry, driving digital movie distribution and transitioning the theatrical industry away from its 100-year old film format. A leading expert on the future of movie distribution and 3D, Mr. Darrow has been a featured panel member at CES 2009, a keynote speaker at 2008’s ShoWest and a recipient of that event’s “Digital Cinema Pioneer Award.”

Laser Light Engines’ investors include Braemar Energy Ventures and Harris & Harris Group.
