Compact, Efficient, High Power Semiconductor Laser for Undersea Communication

Existing gas and solid state green laser technology is not adequate to Navy"s needs for comm due to the large size, weight, cost, inefficiency, complexity. Furthermore, to modulate these lasers at high frequency, expensive and bulky acousto-optical modulators are required. Additionally, the emission wavelength is restricted to the atomic transitions of the gain crystal or gas, typically 532nm or 514nm in the green region. Green laser diodes are an ideal solution, but these are not yet available commercially. Soraa , Inc. is world leader in the development of InGaN green and blue laser diodes and proposes to develop a Compact, Efficient, High Power Semiconductor Laser for Undersea Communication. Soraa has demonstrated world record results in CW green and blue emitting laser diodes:>100mW CW in the 510-520nm range for single mode devices and>4W at 450nm from a laser array. Soraa"s cofounders, Dr. Shuji Nakamura, Dr. Steve Denbaars, and Dr. Jim Speck, performed the first demonstration of a high brightness GaN blue laser diode (LD) and light emitting diode (LED) in the 1990s. Soraa is a US company with a world renown team, strong financial backing, patents, and supply chain to become a strong supplier to the US DoD.
