How To Select A Laser Amplifier:
Welcome to RPMC’s ‘How To Select A Laser Amplifier’ page. Primarily, this page should help you quickly identify an appropriate Laser Amplifier that suites your needs. In short, we explain how we define and organize these products, and how you can use our filters and product table to quickly find viable options to match your requirements.
The difference between Lasers and Amplifiers comes in when we look at where the incident photon comes from. First, in a laser, the resonator “catches” a spontaneously emitted photon. Then, redirects it back into the gain medium over and over again until the laser gain threshold is reached initiating the lasing process. However, in a Laser Amplifier, there is no resonator. Instead, the photons come from an outside source, known as a seed laser, which is then amplified via stimulated emission as it passes through the length of the amplifier. As a result, you can now take a lower power laser with your desired properties and increase its power without affecting it’s overall performance. For example, the seed laser beam would preserve its linewidth, pulse width, beam profile, etc.
RPMC offers a selection of Laser Amplifiers, including both Fiber Amplifiers and DPSS Amplifiers. Indeed, after reading this page, you should have a better understanding on how to select the best Laser Amplifier for your specific needs. Let’s get started!

There are a wide variety of optical amplifiers available on the market. For example, there are semiconductor tapered amplifiers, erbium-doped fiber amplifiers, and diode-pumped solid-state (DPSS) amplifiers, just to name a few. Each “Type” has their advantages and disadvantages. However, we typically view DPSS Amplifiers as the most versatile. For instance, they can be used with a very wide range of Seed Lasers, from high peak power Q-Switched Lasers to Single-Frequency Continuous Wave Laser sources. If you need a Laser Amplifier, knowing which amplifier type you need can be a good place to start. Next, we will explain the differences between the Fiber Amplifiers and DPSS Amplifiers we offer.
We offer a wide selection of Telcordia grade, erbium and ytterbium doped Fiber Amplifiers. Firstly, our various options include Pulsed or Continuous Wave (CW) capabilities, wavelength options ranging from 1030nm to 2050nm, and output powers up to 40W. Finally, they are typically used for various Atom Trapping, Test & Measurement, and Telecom applications.
The DPSS Amplifiers we offer are OEM-type Nd:YAG (1064nm) or Yb:YAG (1030nm). Firstly, depending on the configuration, they have a range of compatibility from CW to femtosecond (fs) pulses, and output powers up to 100W. Finally, they are typically used for enhancing low power oscillators, micromachining applications, or for gravitational wave detection.
Our Fiber and DPSS Laser Amplifiers are available in a range of wavelengths from 1030nm to 2050nm (NIR and SWIR spectral ranges). Filtering for wavelength can be a good way to quickly filter out unnecessary options.
Power Selection & Input Power:
The Power Selection and Input Power filters can help you easily narrow down an appropriate range of options for your requirements. First, you will need an amplifier that can handle the amount of input/seed power from your laser. Second, you will need to ensure the amplifier can provide an appropriate level of amplification to get the output power you need. So, filtering for output power or input power is a good next step.
Our DPSS Amplifiers are available only with Linear Polarization. However, our Fiber Amplifiers provide both Linear and Random Polarization options.
Narrow Linewidth Lasers have a tightly controlled, narrow optical spectrum. Therefore, allowing for a very precise, stabilized wavelength output. Consequently, they are useful for applications like Spectroscopy, Holography, and Interferometry.
If you happen to know of a particular series of lasers, you may simply filter to see all amplifier options for that series.
