A meter is a readout and processing instrument; its connected sensor determines much of the usable measurement range. Begin with wavelength, continuous or pulsed operation, expected power or energy, beam diameter and…
Wavefront sensing is an important part of optical metrology, adaptive optics and alignment. Traditional methods such as Shack–Hartmann sensors and interferometers offer high performance but often require dedicated hardware, careful alignment and…
Laser welding is an important part of laser materials processing. The conduction-mode process discussed here is used for thin-walled materials and lower-speed precision joints: radiation heats the surface, and conduction carries that…
