8-beam local oscillator array at 47 THz generated by a phase grating and a quantum cascade laser

© 2017, OSA - The Optical Society. All rights reserved. We present an 8-beam local oscillator (LO) for the astronomically significant [OI] line at 4.7 THz. The beams are generated using a quantum cascade laser (QCL) in combination with a Fourier phase grating. The grating is fully characterized usin...
