780 nm Single-Frequency Narrow Linewidth Fiber Lasers

Overview Specifications Related Products Order Now!

SIMTRUM provides the 780 nm single-frequency narrow linewidth fiber lasers with an all-fiber scheme that is insensitive to ambient temperature and vibration for applications in atomic laser cooling, entanglement source generation, rubidium atom detection and atomic quantum modulation. It achieves high output power greater than 2 W with 24-hour frequency drift of less than 100 MHz by means of a low-noise seed source, low-noise fiber amplification and high-efficiency frequency doubling conversion.

Features

Single Frequency Without Mode Hopping
High Power Stability
Low Frequency Drift
Excellent Beam Quality

Applications

Entanglement Source Generation
Gravimeters/Gyroscopes/Gravity Gradiometers
Atomic Clocks
Rubidium Detection
Atomic Quantum Regulation
Magnetometers
