Continuous-wave highly-efficient low-divergence terahertz wire lasers
Quantum cascade lasers are compact sources, but simultaneously achieving cw operation, low divergence and single-mode emission has proven difficult. Here, Biasco et al. use a combination of distributed feedback and outcoupling via hole arrays, improving the performance of such a terahertz laser.
