My Laser

A MOPA laser stands for “Master Oscillator Power Amplifier” laser. Let me explain how it works step by step:

1. Master oscillator: First, a high-quality laser beam is created using a master oscillator. This laser beam has low power, but high quality and stability.
2. Amplifier: Next, this laser beam is sent to an amplifier. Here, the power of the beam is increased by using a material that amplifies it. This can be a crystal or a gas.
3. Frequency conversion: When the laser beam is amplified to the desired power, it can go through a frequency conversion process. This means that the wavelength of the laser beam is changed to a different wavelength. This is useful in a variety of applications, such as creating laser light with different colors.
4. Output beam: Finally, the MOPA laser outputs the amplified, frequency-converted laser beam with high power and high quality. This beam can be used for a variety of purposes, such as cutting, welding, marking, or drilling materials.

In summary, a MOPA laser uses a master oscillator to create a high-quality laser beam that is then amplified in an amplifier and can be changed in wavelength before it is output as a powerful laser beam.

Well, (say well like you were Ronald Reagan) now there is a question. I live in the civilised part of the world, where we use metric, but som parts of the evil empire that uses the middle age system where 100 cm or 1 meter equals 3,280839 units of someones feets? So, should I as a good European, use the Queens way of writing it, Fibre.

And to be honest, there is not much in the way of good language skills in this Laser-operator, so i went for the Fiber-Laser.

SPI Lasers is an international company that services businesses and industries all over the world, and so we use the American English spelling, which is “fiber” laser. However, you may find them also referred to as fibre lasers, taking the UK English version. Don’t get confused, they both do the same thing!

So from now on, i will probably write Fiber & Fibre like it was a consulting agency.
