We report the Tilt-Locking (TL) technique applied to lock a laser in pulsed regime to a 28 000 high finesse Fabry–Perot cavity. Preliminary experimental results show that TL technique is comparable with the well-known Pound–Drever–Hall technique. This study is the first to implement the TL technique to lock a pulsed laser to a high-finesse optical cavity. Very high and stable coupling is obtained. The coupling rate is ∼80%, and locking can last for more than 1 h. Furthermore, while previously published papers have focused on near field case, in this study we will give the error signal shape simulation for the far field case. We will show that for different types of error sources, the split photodiode transverse position can be carefully adjusted to obtain a symmetrical error signal. Our experimental results are consistent with the simulations.
