It is shown that a microphone placed in the laser plasma can be used for detection and observation of the optical phenomenon such as an optical feedback in a continuous wave regime of the laser oper...
The energy coupling rate during welding of Al-Mg-Si alloys with a CO2 laser and a Nd:YAG laser was measured calorimetrically. The coupling rate obtained with the Nd:YAG laser was higher than that with...
Bamboo is a regenerative resource, which can regenerate within about 3 years. In the architectural field, bamboo materials have been traditionally applied for a wide variety of purposes. However, the ...
A laser plastic coloring (LPC) method has been newly developed as an innovative coloring method for plastic materials using a CO2 laser system. Irradiating laser beam to water diluted dye, the dye sol...
An optical method of temperature measurement to analyze CO2 laser active medium based on near-infrared absorption spectroscopy with a 1.6-µm distributed-feedback (DFB) semi- conductor laser is d...
A resonator using w-axicon and axicon mirrors for a double coaxial electrode discharge CO2 laser is analyzed using the vector field, iterative reflection method. A uniform ring-shaped output mode is e...
Acoustic response to the CO2 laser pulse generation in the arrangement of the slab-waveguide structure is considered. The velocity of an acoustic wave in the carbon dioxide laser gas medium is calcu...
We analyze the effect of the laser annealing on the crystallization of Er3+ doped amorphous Al2O3 thin films deposited on the silica-on-silicon substrate. These thin films were prepared by the microwa...
In the paper, changes of the optical and thermodynamic parameters, such as a refractive index, pressure, and temperature are investigated on an RF pulsed CO2 slab-waveguide laser. Changes of the refra...
