Narrow linewidth, high stability laser system | Optical lattice clock, cooling atoms
CES/FZW/FSC/MGPA/MFE/XRF
Providing total systems in the field of quantum optics, such as optical lattice clocks and cooling atom experiments.
Optical lattices are a technology that traps cooled atoms in periodic light created by the interference of laser light, serving as the foundation for optical lattice clocks, quantum simulations, and neutral atom-based quantum computers. The realization of a stable optical lattice requires the following four essential components: - A frequency-stable seed light source - High-power, low-noise light amplification - Fast control of intensity and frequency - Monitoring to accurately track absolute wavelength By combining our narrow linewidth lasers, wavelength meters, high-speed servo controllers, and fiber amplifiers, we can construct a consistent laser system for optical lattices, from the seed light source to the beam irradiation on atoms. - No optical axis alignment required due to fiber optic configuration - Capable of long-duration continuous operation - Automatic control from a PC (Ethernet/USB, Python, MATLAB, LabVIEW) Please feel free to consult us even if you have not yet determined the configuration, such as "which wavelength should I choose?" or "how much power is needed?"

Signal flow of the optical lattice laser system: 1. Generate light source with a seed laser. 2. Continuously monitor the absolute wavelength with a wavelength meter. 3. Quickly frequency lock and narrow the linewidth with a servo controller. 4. Amplify up to 20W with a fiber amplifier. 5. Drive the AOM with an RF synthesizer, cancel noise in real-time, and achieve a light lattice with constant intensity. This is a scalable configuration where amplifiers can be selected according to the required power from a single seed.
