mopalaser source

The MOPA (Master Oscillator-Power Amplifier) laser source is a more technical laser structure formed by combining an oscillator with an amplifier. Nadia and Yevgeniy are both heads of their respective technical projects at Laser Micro-Machining (LMM Wi and LMM Classic) in Russia and the USA, which span from sub-micron manufacturing (LIGA, micro-stamping) to the design of new laser systems that guarantee precise and high-energy output for remote continuous wave and pulsed lasers, and are very versatile in a range of industrial applications including marking, engraving, and cleaning of a range of materials. MOPA fiber laser is a specific kind of nanosecond pulse fiber laser which consist of a semiconductor laser seed source and a fiber amplifier excited electrically with pulses. It features independently adjustable output pulse width from 2 ns ~ 500 ns, repetition frequency up to megahertz, with a wide parameter adjustment range to cover (a) conventional processing and (b) precision proc

High Power: MOPA systems can output tightly packed laser power that is necessary for applications needing high energy density like laser cutting and deep engraving.

Operating Modes: Comparing laser systems, MOPA lasers can have wider applications than other lasers, such as in materials processing and delicate machining, due to their variable pulse width and frequency option.

Burst Energy: MOPA lasers can adjust to deliver high energy in bursts, adequate for processing materials at a higher speed rate while transferring the energy more efficiently to the material surface.

These systems often produce high quality Gaussian beams and can be focused tightly to meet your precise machining/marking needs.

MOPA laser sources generate a highly stable output, a key reason for their use in production and industrial applications with extensive operations that require precision over time.
