Ultimate Guide to MOPA Laser Marking Technology-HeatSign

In this article, you’ll learn all about MOPA fiber lasers. You will also get a guide on how to buy one for your business and what’s best in that category.

Lasers are significant innovations that perform an essential part in many industries, including automotive, medical, aerospace, oil & gas, electronics, and more. Among these innovations, the MOPA laser is a great invention, that can mark, engrave etch products for credentials, or decorative purposes.

The MOPA laser generates a power source that provides more amplitude and pulse frequency from 1 to 4000 kHz. It has different engraving effects over metal and plastics as compared to fiber Q-switched lasers technology.

MOPA laser offers an amazing solution for better finishing on plastic materials and etching different colors on titanium, stainless steel, or aluminum. With this technology, you can efficiently expand the possibilities of marking metals and plastics.

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 maintaining high repetition rates at high power output. In brief, MOPA fiber laser provides separate tuning on 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 that results in more feasibilities 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 neglect 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 adjust an optical modulator between the seed laser and power amplifier

What materials can a MOPA Laser engrave?

The MOPA laser marking machine can engrave over:

• Gold
• Brass
• Silver
• Nickel
• Metals
• Copper
• Carbide
• Titanium
• Platinum
• Tungsten
• Aluminum
• PC plastic
• PLA plastic
• PBT plastic
• ABS plastic

How does MOPA Laser Marking Machine Work?

Marking machines satisfy the requirement for identification and traceability of material by creating a permanent or temporary mark. The MOPA configuration consists of two gas discharge chambers:

• The master oscillator is a single-frequency laser that is used to insert lock lasers and the optical amplifier
• The power amplifier improves light to boost the output power

Surface oxidation is the principle of laser color etching. Scientifically in the presence of air, material surfaces react to develop thin oxide layers. The material surface is heated by using a laser beam, to form a thin oxide film.

After maintaining the material surface temperature, you can get a uniform color. The intensity of the oxide layer grows to forms a thin film impression. The oxide layer is useful to protect the material against scratching and corrosion.

The color laser etching for acrylic is achieved by adding a color dye powder. This works with regular engraving then pressing a special powder on the engraved material by laser machine.

What is a MOPA Fiber Laser?

The master oscillator generates a highly stable beam that is amplified by the optical amplifier to boost the output power. If the laser system comprises a fiber amplifier to increase the output power, it is termed master oscillator fiber amplifiers (MOFA).

MOPA fiber lasers can modify and increase the output power without altering the geometry or performance to achieve power scaling. With these fiber lasers you can mark and engrave on different types of surfaces and materials.

These lasers use semiconductor diodes and a doped fiber optic cable that works as the resonator and gains medium. The gain medium also contains rare-earth elements like ytterbium, erbium, dysprosium, neodymium, thulium and praseodymium. MOPA fiber lasers are reliable and efficient technology.

MOPA Fiber Laser Marking Machine

The MOPA fiber laser marking machines use Q-switched technology that supports the power supplier to produce the path light within 1 to 500 kHz. It shows great effects for marking metal, for example, stainless steel, silver jewelry, gold, anodized aluminum, and metal alloy, etc.

The MOPA fiber laser marking machine marks black color on the Anodized aluminum metal. The price of the MOPA fiber laser marker is somewhat higher so if you don’t need black color marking on anodized aluminum, then choose a common fiber laser marking machine.

The fiber laser marker is compatible with software such as AutoCAD, Photoshop; PLT, DXF, BMP and PCX, etc. It produces a higher rate of marking speed over plastics and metal materials.

What are the advantages of a Fiber Laser Marking Machine?

Fiber laser marking machine gives the ideal solution for etching metals, plastics, nickel plating, and many other materials. The MOPA laser provides versatility in combinations of laser parameters and can be perfectly adjustable to the material.
