New Method of Frequency Stabilization of Semiconductor Lasers : Waves, Optics and Quantum Electronics

概要

論文の詳細を見る
It is demonstrated that the frequency of a semiconductor laser driven by a constant current can be stabilized by controlling the operating temperature so as to give a constant operating voltage. Since the operating voltage is a direct monitor of the operating temperature, the frequency thus stabilized is insensitive to ambient temperature variations. For hermetically unsealed near-infrared lasers the frequency stability is within ±350 MHz under normal laboratory conditions and the shift is only 500 MHz for a 10℃ variation in the ambient temperature, A resettability of ±350 MHz is obtained with an adjustment-free operation.
