摘要： In a high velocity gas laser oscillator of radio frequency or microwave exciting type, both end parts of the discharge tube are provided with gas flow rectifiers for making an inward flowing whirlwind at the discharge region of the discharge tube by blowing the discharge gas through plural slits located in a plane disposed at a predetermined angle with respect to a plane including axis of the discharge tube, wherein microwave power is applied to the discharge tube so as to define an annular discharge region in the discharge tube.

摘要： In an analog multiplying-averaging circuit for detecting very small mean power in a wide band and a wattmeter using the circuit, a first voltage signal is inputted to a base and a second voltage signal is inputted to a collector of one transistor circuit of a first differential amplifier, to supply a power corresponding to the multiplying-averaging of the two input signals to the collector of the transistor circuit. A base and a collector of another transistor circuit of the first amplifier are grounded to extract a DC collector voltage corresponding to junction temperature differences produced between the two transistor circuits from the collector of the other transistor circuit. A second amplifier is provided, which also has two transistor circuits. A base of one transistor circuit of the second differential amplifier is grounded. The second voltage signal is inputted to a collector of the one transistor circuit, and a base and a collector of another transistor circuit of the second amplifier are grounded to also extract a DC collector voltage corresponding to junction temperature differences of the two transistor circuits from the collector of the other transistor circuit of the second amplifier. From the two DC collector voltages, a signal corresponding to the multiplying-averaging of two input signals is obtained.
