Abstract: A single-frequency Ti:sapphire laser has been stabilized to a reference cavity with the simple side-of-fringe locking technique and a piezo-controlled mirror as compensating element. A frequency stability of 1 kHz rms with respect to the locking etalon is obtained. This Ti:sapphire laser, optimized for 972.5 nm, will be used for two-photon excitation of the 2S–4S transition in atomic hydrogen.
