WebLasers can be divided into three main categories: continuous wave (CW), pulsed, and ultrafast. As their name suggests, continuous-wave lasers produce a continuous, uninterrupted beam of light, ideally with a very stable output power. The exact wavelength (s) or line (s) at which this occurs is determined by the characteristics of the laser medium. WebThe word ‘laser’ is actually an acronym that stands for light amplification by stimulated radiation emission. These devices create highly-concentrated beams of light by constantly stimulating and adding more energy to weak like waves until they grow in intensity. popular money lending for tools
