Beatin' Those Low-Power Blue Laser Blues...Good news for fans of home theaters: Projection displays stand to get a lot brighter--and cheaper--with a new, compact blue laser developed by Gemfire Corporation (Palo Alto, CA). The company's technology is scalable, which means multiple blue lasers could be combined into high-power arrays that are more efficient and brighter than conventional projection methods. It will also cost much less than existing blue-green lasers because the design uses low-cost, frequency-doubled infrared (IR) diode lasers. In addition to projection displays, the blue laser could enable higher-density optical data storage devices. BMDO funded Gemfire to develop this laser for use in data storage systems for battlefield management applications.

Gemfire's innovation uses a 830-nanometer (nm) IR diode laser and a second-harmonic generator (frequency doubler) to create a 415-nm beam. Output beams anywhere in the visible spectrum are possible by varying the input IR laser wavelength. The key component of the blue laser source is a 0.5 H 5 H 15-millimeter chip of lithium niobate (LiNbO3) material. The diode laser irradiates a polarization rotator integrated on the LiNbO3 chip, which changes the light's polarization from horizontal to vertical. Then, the light's frequency is doubled by the second-harmonic generator, which halves the wavelength to produce blue light.

Focusing on the lucrative projection display market, Gemfire has already created a 20-milliwatt prototype laser, which is available for demonstration. It currently is seeking display manufacturers and other companies interested in making full-color projection displays. Once its presence in the display market is established, Gemfire will investigate other potential markets in which the company can compete by mass-producing low-cost blue lasers.

Dear Steve and all: Before you all get excited about IBM let me tell you something. I was a consultant to a company that accepted "help" from IBM for IBM getting 50% of the company. WELL, IBM set up the circumstances so that they STOLE the other 50%, I dont have the space here to get into the details. BUT, in talking to an attorney over all of that I learned that THIS ATTORNEY now in private practice used to be one of the MANY that IBM has employed full time. He told me that IBM pulled so many crooked deals like that he could NO LONGER STOMACH it and left them. When things get too gross for even an attorney, they must be bad. So, the bottom line is this, I hope that MVIS NEVER meets IBM. JDN
