Two-color heterolasers as parametric generators of infrared radiation Academic Article uri icon


  • A new scheme for generation of coherent radiation on the intersubband transition without population inversion between subbands is presented. The scheme is based on the resonant nonlinear mixing of the optical laser fields on the two interband transitions that are generated in the same active region and serve as a coherent drive for the infrared field. The two-wavelength lasing on the interband transitions can be achieved at substantially lower threshold current than population inversion and gain on the intersubband transition. This may ensure stable high-power room-temperature operation. Due to parametric, inversionless nature of generation, the proposed lasers are especially promising for the long-wavelength operation above 20 micron.
