Application of an atomic magnetometer based on nonlinear magneto-optical rotation(NMOR) was studied. We have observed the NMOR signals in 87Rb D1 line using the the Rb vapor cell coated with paraffin. The paraffin coated vapor cell lead to double structured features in the NMOR signal which have different slope value of 0.193 mrad/mG and 2.23 mrad/mG with laser power 400 μW, respectively.

A design and new theoretical model of a quantum dot (QD) microcaity laser operating at 1 THz is proposed based on a semiconductor QD gain medium, where the lasing occurs through discrete conduction states. Our calculations show that a significant population inversion and frequency as low as 1 THz can be reached can be achieved. It is concluded that it maybe serve as a terahertz laser.
