Laser lamps are mercury-free gas discharge lamps used to pump solid-state lasers in many laser applications like welding cutting and marking.They are especially suitable for high-power lasers or lasers with high precision
This paper describes the results of optimising three process variables (control factors) to achieve a narrow line width in laser engraving of ITO conductive coatings using the Taguchi technique of experimental design.
A beam of finite diameter is focused by a lens to obtain a smaller beam spot. If the diameter of the focused spot d0 is defined as the diameter which contains 86% of the focused energy the focus spot size is determined by
This paper presents a high-efficiency Nd:YVO4 laser end-pumped by a 15W diode laser bar. An optical-optical efficiency as high as 42% and an output laser power of over 3W were obtained with a beam quality factor M2 of less than 1.2 and an ou
The first CO2 laser operated at the wavelength of 10.6m in 1964. Because it is one of the most efficient lasers with 10% conversion efficiency for commercial models it is widely used in laser cutting welding drilling and surface treatment
The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens.The Galilean telescope is most often employed due to its simplicity small package size and lo
The laser marking systems using different lasers and optical delivery systems may be used to mark an almost endless list of materials including metals plastics ceramics glass wood and leather as well as painted surfaces and photographic e
