摘要: We have investigated the optical pumping effects of single-resonance (SROP) and double-resonance (DROP) in ladder-type electromagnetically induced transparency (EIT) 5S1/2–5P3/2–5D3/2 transition 87Rb atoms. In 5S1/2(F = 2)–5P3/2(F' 3)–5D3/2(F'' 2, 3) with cycling transition, we observed transmittance spectrum due to DROP EIT. Based on our experimental results according laser power (the probe coupling) coupling detuning, revealed that was significant for spectrum. Particularly, 1, 2)–5D3/2(F'' 1) without a two-photon absorption atomic coherence, when weak strong.
