Applications of High-Power Pulsed Diode Lasers

A division of a Asian automotive manufacturer was considering a new technology for an improved driver for high-power short-pulse diode lasers. SRI was asked to assess the validity of the technical, application, and market claims of the inventors. SRI scientists, assisted by laser technology specialists at Sarnoff Corporation, used their knowledge of the physics and technology of laser systems to evaluate the state-of-the-art and the technical advantages of the proposed new technology. SRIC-BI industry experts conducted a literature review and telephone interviews with automobile manufacturers and original-equipment-manufacturers (OEM) to gain market information. SRI's US, Europe, and East-Asia offices provided world-wide coverage of applications, markets, and existing technology development activities.

The application with the largest market potential was laser-based (LIDAR) sensing of range and closing speed for automobiles and other vehicles. LIDAR and microwave (RADAR) sensing systems are already under active development. SRI professionals compared the technical and market advantages of the LIDAR and RADAR technologies. Of equal business importance is the evolution of customer acceptance, government regulations, and resolution of liability issues for collision avoidance, collision warning, and autonomous intelligent cruise control applications.

Additional nonautomotive applications and markets were considered, including aircraft and helicopter obstacle detection, lasers in vision sensors, laser-based materiels processing, laser-based medical equipment, wireless communications, and other applications of rangefinding.

The overall conclusion of the SRI study was that the proposed new laser driver technology offered at most marginal advantages in the applications investigated and thus a limited market opportunity. SRI advised that the Client should proceed with caution.
