| Abstract: | A scheme for a far-infrared fountain laser on transitions between subbands of dimensional quantization in the conduction band in a AlGaAs heterostructure with quantum wells, generating an electromagnetic field in the far-infrared range, is proposed. It is shown that such a device can operate at room temperature using radiation of a CO2 laser or several mid-infrared quantum cascade lasers as pump radiation. |
