continuous-wave laser

A continuous-wave (CW) laser produces a steady, unbroken beam of light by continuously generating laser energy. Unlike pulsed lasers that emit light in short bursts, CW lasers emit a constant stream, making them ideal for precise measurements, communications, and cutting tasks. They work by exciting atoms or molecules inside a laser medium, which then release light in a coherent and monochromatic manner. This steady output allows for consistent power and beam quality, making CW lasers versatile tools in scientific, industrial, and medical applications.
