The steps outlined in this application note can be used to stabilize a TLB-7000, TLB-6900, or TLB-6300 series tunable diode laser to a reference cavity using the Pound-Drever-Hall stabilization technique. For a first attempt at active laser stabilization, it is recommended that one begins with a reference cavity linewidth much broader than the free-running linewidth of the laser. This application note should be considered only as a starting point for laser stabilization, as more advanced servo designs and careful engineering of the reference cavity construction and mounting are required to achieve optimum performance.
