This week’s scientific seminar will be held in the conference room at 11:00 12.02.2016 in the conference room. This 
time there will be two reports:
1) Ravil Urmancheev will update the colleagues on the current research progress in «Area theorem for complicated absorption line»
2) Mansur Minnegaliev is going to present “Review of optical spectroscopy works regarding Pr: LiYF4”
19 of November in the Conference hall of our center at 14:30 Laboratory of quantum memory started their weekly seminar sessions. The first presentation was devoted to the Er3+:Y2SiO5 famous for its homogeneous absorption linewidth of only 73 Hz, which is thinner than in any other known solid state material. The presentation «An overview of properties of Er3+:Y2SiO5 for photon echo» by Ravil Urmancheev touched on the properties of 4I15/2 -> 4I13/2 transition in Er.
