Frequency Locking of a 3.5 Thz Quantum Cascade Laser Using a Gas Cell
We report a frequency locking experiment of a 3.5 THz third-order distributed feedback quantum cascade laser (QCL) by using a molecular absorption line of methanol (CH[subscript 3]OH) gas. With the help of the absorption line, the frequency noise of the QCL is transformed into measurable amplitude f...
