Terahertz amplification and lasing in pump-probe experiments with hyperbolic polaritons in h-BN

Khachatur G. Nazaryan, Ivan Ridkokasha, Marios H. Michael +1

We discuss terahertz pump-probe experiments in hBN from the perspective of Floquet optical materials and photonic time crystals. Anisotropic nature of this material results in a la…
