    In this paper we discuss the possibilities and realization in high-power systems of a narrow-band reflector with adjustable high reflectivity and with continuous tuning over a large frequency region. We describe a design for both low- and high-gain systems. For the experimental realization of a low-gain system we used a CO2laser and studied a continuous range of 65 transitions of the View full abstract»

    This correspondence reports on the successful operation of a TEA CO2laser at rates up to 1000 pps with an average output power up to 65 W over long periods of time. An essential feature of the present system is a rapid gas circulation transverse to the laser axis combined with a large volume of ambient gas. It is found that decomposition of the gas is one of the major problems at high r... View full abstract»

    The possibility of transverse mode locking using cylindrically symmetric laser modes is considered. For a specified set of mode amplitudes and phases it is found that the beam intensity profile in the transverse plane is the same shape as the fundamental mode, but has a spot size that is time varying with the transverse-mode spacing frequency. The beam power is the sum of the powers of the individ... View full abstract»

    A scheme for detecting millimeter- and submillimeter-wave radiation by utilizing a paramagnetic material is described. An analysis of the scheme, which indicates the dependence of the noise-equivalent power on various parameters is given. Experimental results obtained at 35 and 50 GHz are presented. The scheme can be extended to higher frequencies by choosing the proper material and coupling struc... View full abstract»
