High-power multibeam CO2 laser for industrial applications

A green route to preparation of silica powders with rice husk ash and waste gas

“…Removal of CO 2 from different industrial gas streams is becoming increasingly important in recent years. Several papers have reported the utilization of CO 2 gas for various applications like power generation, natural gas, stack gas and heating as well as closed-circuit breathing systems for use in confined spaces such as manned space shuttles [33][34][35][36][37]. The recovered CO 2 , with different degrees of purity, has also numerous applications in the chemical industry.…”

Longitudinally Excited CO2 Laser

“…Additionally, high output power can be provided by a multi-path system folding back the optical path in the resonator and a multi-beam system which uses multi-tubes. High power DC-CO2 laser emitting CW power of 1 kW using 20 discharge tubes with the inner diameter of 9 mm and the length of 195 cm has been reported (Deshmukh & Rajagopalan, 2003).…”
