The frequency stabilization of a laser diode in the 1.3 microm region using double resonance optical pumping (DROP) spectrum in the 5P(3/2)-6S(1/2) transition of (87)Rb atoms is demonstrated. The signal-to-noise ratio of the DROP spectrum is approximately ten times higher than that of the previous optical-optical double resonance spectrum. The spectral linewidth of the DROP measures 8.4 MHz. When the frequency of a 1.367 microm laser diode is stabilized to the DROP spectrum, the frequency stability is 9 x 10(-12) after 100 s. Also, the wavelength of the frequency-stabilized laser locked to the 5P(3/2)-6S(1/2) transition using a wavelength meter is measured.
展示了利用（87）Rb原子5P（3/2）-6S（1/2）跃迁中的双共振光泵浦（DROP）光谱，对1.3微米区域的激光二极管进行频率稳定。DROP光谱的信噪比大约比先前的光-光双共振光谱高十倍。DROP的谱线宽度为8.4兆赫兹。当1.367微米激光二极管的频率稳定到DROP光谱时，100秒后的频率稳定性为9×10^(-12)。此外，还测量了使用波长计锁定到5P（3/2）-6S（1/2）跃迁的频率稳定激光的波长。
