Nano-composite Semiconductor Lasers

Polycrystalline ceramics as laser gain hosts have several remarkable advantages over single crystal ones. For example, they can house a higher doping concentration, are much easier to be fabricated into larger and more complex shapes, which is extremely difficult in the crystal case. The costs of the ceramic laser materials could be much lower than those of single crystals because of the shortened fabrication process and large size, mass production. Boston Applied Technologies Incorporated (BATi) proposes to develop highly desired high power semiconductor nano-composite laser via a safe, low-cost and reliable chemical solution nano-powder preparation route and hot-press densification process with our extensive experience and unique fabrication techniques. The modified solvothermal route will enable the synthesis of nano-composite powders with uniform sizes and low impurities, which are crucial for realizing a transparent ceramic semiconductor laser gain medium.
