EIT at 52S1/2→62P3/2 transition in a mismatched V-type rubidium system

Induced transparency on a blue probe light in a Doppler broadened V-type mismatched system using a low power near infrared coupling diode laser was experimentally observed. Extensive theoretical model was used which utilizes the three-level V-type scheme. Appropriate modifications were made to take into account the hyperfine splitting of the ground 52S1/2 and excited 52P3/2 and 62P3/2 states. Calculated probe absorption line profiles reproduce with great accuracy measured absorption profiles. The influence of the 52P3/2–62P3/2 unlinked states coherence on the induced transparency was discussed in the context of the used theoretical model.
