Single-frequency fiber laser for highest spectral precision
The single-frequency fiber lasers and fiber amplifiers from MPB Communications were developed for applications that require a extremely narrow linewidth, low noise and a high coherence length require. The portfolio includes seed lasers, visible and infrared fiber lasers, and high-power fiber amplifiers for demanding applications in research and precision metrology.
With line widths of <100 kHz for the single-frequency fiber lasers and <50kHz For the seed lasers, highly coherent laser sources are available for spectroscopic, interferometric, and quantum optical applications.
Single-Frequency Seed Fiber Laser
The compact single-frequency seed fiber lasers form a highly stable laser source for applications with particularly high requirements for line width and coherence.
MPB offers:
- Wavelengths of 910 to 1950 nm
- Output powers of 5 to 50 mW
- line width <50kHz
The seed lasers are suitable both as standalone narrowband laser sources and as a master oscillator for downstream amplifier systems.
Single-frequency fiber lasers in the visible spectral range
Single-frequency systems with various power levels are available for applications in the visible spectrum.
Visible Fiber Lasers:
- 460 to 790 nm
- Output power up to 5 W
- line width <100 kHz
High Power Visible Fiber Laser Systems:
- 532 to 671 nm
- Output power up to 10W
- line width <100 kHz
MPB thus combines high output powers in the visible spectral range with the spectral purity required for single-frequency applications.
Single-frequency fiber lasers in the NIR
The infrared single-frequency fiber lasers cover wavelengths from 920 to 1900 nm from and achieve output powers up to 30 W at line widths of <100 kHz.
The combination of high performance, narrow linewidth, and fiber-based architecture enables its use as a highly coherent laser source for demanding scientific and optical systems.
Single-frequency fiber amplifier
For applications where the performance of an existing single-frequency laser source is to be increased, MPB offers corresponding fiber amplifiers.
Available areas:
- IR 1100–1530 nm, to 15 W
- Visible 550–765 nm, to 5 W
This allows narrowband seed lasers to be amplified to higher output powers and integrated into complex laser and measurement systems.
Typical applications
The high coherence and narrow linewidth make the single-frequency lasers and amplifiers particularly interesting for:
- Quantum technologies and quantum optics
- Quantum Frequency Conversion
- High-resolution spectroscopy
- interferometry
- Precision measurement technology
- Coherent optical methods
- Atomic and Molecular Physics
- Research and Development
MPB documents, for example, the use of a 1343-nm Single-Frequency Raman Fiber Amplifiers at the University of Maryland for Quantum Frequency Conversion. Another Raman fiber amplifier was used in a high-power UV laser system for coherent Rydberg excitation of ytterbium.
Single-frequency fiber lasers and amplifiers from MPB Communications
With line widths down to 50 kHz, wavelengths from the visible spectral range to 1950 nm and output powers up to 30 W MPB offers a versatile portfolio of highly coherent fiber lasers and amplifiers for particularly demanding optical applications.
Soliton assists you in selecting and configuring the suitable system. Decisive factors in particular are wavelength, line width, output power, required coherence, and the question of whether a seed laser, a complete laser system, or a fiber amplifier is needed.
