16.As can be seen from threshold current in function of magnetic field, laser action is present for sample A2770 also in the region 3–3.7 T, where resonance conditions occur simultaneously. Here the value of the threshold current is higher than the one at zero field because lifetime modulations do not cooperate.
17.The expression of the gain cross section is where and For sample A2664, we used the values and while for sample A2770, the values were and These numbers yield and respectively. See also J.
