What is a MOPA Laser?

The Master Oscillator Power Amplifier (MOPA) refers to a configuration that consists of a master laser and an optical amplifier to improve the output power. The MOPA fiber laser is an innovative and advanced system that helps to get an amazingly efficient way for your investment.

It is a flexible system that can be used for pulse duration, and to simulate the features of traditional fiber lasers. The marking machines use a modulated seed laser to promote dynamic oscillation parameters. MOPA lasers are recommended for high power output and pulsing frequency ranges.

The MOPA arrangement provides better hold over peak power and pulse width by pulse tune functions that maintain high repetition rates at high power output. In brief, the MOPA fiber laser provides separate tuning for altering laser parameters. This system is usually optimized to generate quality colors and a prominent visual impression.

What are the advantages of MOPA laser for your application?

MOPA configuration is principally more complicated than a laser. The heat-affected zone is reduced for lower pulse energy which results in more feasibility for laser marking of metals and plastics. The MOPA concept can have certain advantages:

  • MOPA lasers provide the highest beam quality and long diode life

  • The optical intensities are low amplifier, as compared to intensities in a laser

  • A gain-switched laser diode gives more flexibility that can be favorable to neglecting the additional optical elements

  • It is simple to combine an existing laser with an existing amplifier instead of developing a higher output power laser

  • It is simpler to achieve the expected performance with a MOPA instead of a laser e.g. the required power is high for linewidth, beam quality, wavelength tuning range, or pulse duration

  • It may be useful to modulate the low-power seed laser by adjusting the amplifier’s pump power or adjusting an optical modulator between the seed laser and the power amplifier
