RFA

High power, single-frequency, CW Raman fiber amplifier

Our highly reliable Raman fiber amplifiers (RFA) are based on patented technology. With their high power of up to 30 W the amplifiers cover the wavelength range from 1120 to 1370 nm that is not accessible by Yb or Er fiber amplifiers. The RFA is designed using TOPTICA’s high quality engineering excellence and utilizing a stable European & North American supply chain. The all fiber design requires no re-alignment and provides a high degree of stability. The RFA offers a wide tuning range of up to 10nm, a relative intensity noise <1% RMS (10 Hz- 10 MHz) and excellent long term RMS power stability of less than 0.5 % over 100 hours (with a TA pro seed laser).

The RFA is utilising the proven and stable DL pro or TA pro as a seed laser, enabling a seamless integration into the TOPTICA environment of for example wavelength stabilization options.

The system consists of two modules:

The Fiber Pump Module: Providing pump light for the RFA module
The Raman Fiber Amplifier Module: High power amplifier module with inputs from the pump module and the seed laser

Applications

Quantum physics science

TOPTICA's products are widely and successfully used for scientific applications in fundamental quantum technology. In these fields quantum physics, quantum optics, atom optics, photonics, statistical physics and related fields are investigated in order to understand the basics of quantum technology.

Quantum computing & simulation

Lasers are used to realize most of the quantum systems used for quantum computing and simulation. Lasers are utilized to prepare quantum states, to realize quantum gates, and to read out qubits. In addition, lasers are used to link different quantum systems (e.g. to connect quantum computers or quantum computing subunits), a major task of quantum communication. Tunable diode lasers, fiber amplifiers, optical frequency combs, and wavelength meters, ideally combined in laser rack systems as complete solutions, are the most important products.

Quantum communication

Quantum communication is redefining how information is transmitted, secured, and trusted. At the heart of this technological revolution are high-performance laser systems that generate, control, and stabilize light at the quantum level.

Quantum sensing & metrology

Just often we don't realize it in normal life. This is because quantum systems are usually too tiny and are often destroyed in their key properties or their quantum-ness by even subtlest changes in the environment.

Lithography & microfabrication

From semiconductor patterning and 3D microprinting to holographic optics and transparent displays, laser light is the most precise tool.

Semicon inspection & metrology

Laser-based metrology and inspection have become indispensable tools for shrinking feature sizes, more and thinner layers, as well as increasing chip and package areas.

Options

Frequency doubling

To reach visible wavelengths the RFA can be integrated with TOPTICA 's SHG portfolio of frequency doubling systems. With these, high power in the visible wavelengths (for example more than 15W at 589nm) can be achieved while maintaining tunability over the entire RFA tuning range.

Frequency quadrupling

To reach UV wavelengths the RFA can be integrated with TOPTICA 's FHG portfolio of frequency quadrupling systems. Drawing on TOPTICA’s extensive experience of custom (D)UV systems and maintaining tunability over the entire RFA tuning range.

Additional wavelengths

For wavelengths outside this range please enquire for a custom system.

Third party seed laser

Utilizing a third party seed laser of your choice is possible. Please inquire for requirements.
