摘要：
We report room-temperature operation of lambda approximate to 3.7 mu m lattice-matched InGaAs/AlInAs/InP quantum cascade lasers based on frequency doubling with similar to 2mW/W-2 conversion efficiencies. Similar devices based on 1% strain-compensated materials can operate at lambda=3-3.7 mu m. (C) 2009 Optical Society of America
