Sheaumann’s monolithic MOPA technology creates a tapered semiconductor laser for emerging applications, including lidar for autonomous vehicles.
Multimode semiconductor laser diodes with >10 W output are readily available. However, single-mode lasers that can operate at such power levels without optical pumping have only previously been created in university or government laboratories. Sheaumann is working to create a commercially viable, monolithic master oscillator power amplifier (MOPA) in the form of a tapered laser with power levels of more than 8 W with true single-longitudinal-mode operation. This is one of the first-ever attempts to develop a manufacturable, robust, and reliable commercial tapered laser, especially at this power.
