How To Select A Laser Amplifier:

Laser AmplifiersWelcome to RPMC’s ‘How To Select A Laser Amplifier’ page. This page is designed to help you quickly identify an appropriate Laser Amplifier that suites your needs by explaining 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.  In a laser, the resonator “catches” a spontaneously emitted photon and then redirects it back into the gain medium over and over again until the laser gain threshold is reached initiating the lasing process.  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 (linewidth, pulse width, beam profile, etc.) and increase its power without affecting it’s overall performance.

RPMC offers a selection of Laser Amplifiers, including both Fiber Amplifiers and DPSS Amplifiers. 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!

Amplifier Type:

There are a wide variety of optical amplifiers available on the market, including semiconductor tapered amplifiers, erbium-doped fiber amplifiers, and diode pumped solid state (DPSS) amplifiers, just to name a few.  While each “Type” has their advantages and disadvantages, DPSS Amplifiers are typically viewed as the most versatile because they can be used with a very wide range of Seed Lasers ranging 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. Here we will explain the differences between the Fiber Amplifiers and DPSS Amplifiers we offer.

Fiber Amplifiers:

We offer a wide selection of Telcordia grade, erbium and ytterbium doped Fiber Amplifiers, with Pulsed or Continuous Wave (CW) capabilities, wavelength options ranging from 1030nm to 2050nm, output powers up to 40dBm (10W), and they are typically used for various Atom Trapping, Test & Measurement, and Telecom applications.

DPSS Amplifiers:

The DPSS Amplifiers we offer are OEM-type Nd:YAG (1064nm) or Yb:YAG (1030nm) and, depending on the configuration, have a range of compatibility from CW to femtosecond (fs) pulses, output powers up to 100W, and are typically used for enhancing low power oscillators, micromachining applications, or for gravitational wave detection.

Wavelength Selection:

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. You will need an amplifier that can handle the amount of input/seed power from your laser, and you will need to ensure the amplifier can provide an appropriate level of amplification to get the output power you need.

Polarization:

Our DPSS Amplifiers are available with Linear Polarization. Our Fiber Amplifiers are available with both Linear and Random Polarization.

Linewidth:

Narrow Linewidth Lasers have a tightly controlled, narrow optical spectrum, allowing for a very precise, stabilized wavelength output, and they are useful for applications like Spectroscopy, Holography, and Interferometry.

Manufacturer & Series:

If you happen to know of a particular manufacturer, or more specifically, a particular series of lasers, you may simply filter to see all pulsed options for that manufacturer or series.
