Far-infrared generation by CO2 lasers frequencies subtraction in a ZnGeP2 crystal

A pulsed radiation power of approximately 1 W was reached for the first time, with the aid of a ZnGeP2 crystal, at the difference frequency of CO2 lasers radiation in the submillimeter spectral range.

Far infrared generation by CO2 lasers frequencies subtraction in a ZnGeP2 crystal

Abstracta pulsed radiation power of the order of 1W in the submillimeter range (102–110 µm) was reached for the first time, with the aid of a ZnGeP2 crystal, at the difference frequency of CO2 laser radiations.

ATM GDL: new prospects for gas-dynamic laser

At present, a mobile, self-contained laser rated at 50-70 kW or higher is required for solution of a whole range of urgent problems of technology and environment protection.

AMT GDL : power supply independent, mobile, gas-dynamic laser for industrial application

A brief comparison of various types of lasers of 50 - 100 kW power range for industrial use is presented, taking into account the most important technical and economic details. Listed is consumption of fuel, gas components, water, atmospheric air, also electric power required for some of lasers described. Its emphasized that the most prospective is high power laser of gas-dynamic type. It is featured by the outstanding weight-dimensions and specific characteristics. Essential advantage of the proposed gas-dynamic mobile laser is independence of stationary supply of electric power generally required for other types. Combined with independence of electric power plant, the totality of its technical properties, reliability and relatively low operation expenses makes it especially attractive solution of wide range of technological problems like worn reactors utilization, heavy- gauge metal cutting, thin oil films water pollution, etc., namely by means of autonomous mobile technological gas-dynamic laser (AMT GDL).
