| 摘 要： | A simple three-level system is proposed to produce high index of refraction with zero absorption in an Er^3＋-doped yttrium aluminium garnet （YAG） crystal, which is achieved for a probe field between the excited state 4I13/2 and ground state 4I15/2 by adjusting a strong coherent driving field between the upper excited state 4I11/2 and 4I15/2. It is found that the changes of the frequency of the coherent driving field and the concentration of Er^3＋ ions in the YAG crystal can maximize the index of refraction accompanied by vanishing absorption. This result could be useful for the dispersion compensation in fibre communication, laser particle acceleration, high precision magnetometry and so on.

| Abstract: | A simple three-level system is proposed to produce high index of refraction with
zero absorption in an Er3+-doped yttrium aluminium garnet (YAG) crystal,
which is achieved for a probe field between the excited state 4I13/2
and ground state 4I15/2 by adjusting a strong coherent driving field
between the upper excited state 4I11/2 and 4I15/2. It is
found that the changes of the frequency of the coherent driving field and the
concentration of Er3+ ions in the YAG crystal can maximize the index of
refraction accompanied by vanishing absorption. This result could be useful for the
dispersion compensation in fibre communication, laser particle acceleration, high
precision magnetometry and so on. |
