kHz-class linewidth
Keep the source narrow relative to the transition and lock scheme.
Control with precision · Quantum & coherent research
Cold atoms and quantum optics
Address narrow transitions without letting the source become the experiment.
Application focuskHz-class linewidth
Frequency stability
Define drift and tuning over the experiment timescale.
RIN & polarization
Intensity and polarization noise affect preparation and readout.
Why the source matters
Quantum work is usually limited by linewidth, frequency drift, relative intensity noise, and beam quality rather than catalogue power alone.
The correct source is defined at the sample or process—not at the laser aperture. Wavelength and operating mode set the interaction; stability, delivery, timing, and control determine whether it stays useful in the complete system.

Application workflow
Design from the result backward.
Three decisions turn the application into a practical source specification.
Name the transition
Start with exact wavelength, isotope or system, detuning range, and power at the atoms.
Set the frequency budget
Allocate linewidth, short-term noise, drift, tuning, locking, and modulation requirements.
Design the beam network
Plan polarization, splitting, amplification, fiber delivery, AOM or EOM interfaces, and monitoring.
Selection guide
Match the architecture to the experiment.
These are starting architectures. Precisometer qualifies the final wavelength, output, delivery, control, and integration package against your setup.
- Wavelength band
- Visible and NIR single-frequency options, including 633 and 780 nm classes
- Operating mode
- Single-frequency, kHz linewidth, low RIN
Direct narrow-line source
Choose single-frequency DPSS or fiber when the native wavelength meets the transition.
Seed architecture
Use a narrow seed with amplification when linewidth must be preserved at higher power.
Locked experiment
Specify tuning actuators, modulation access, isolation, and monitor outputs with the lock strategy.
Source architecture
Platform families to qualify.
UV, visible, NIR, and fiber laser options
Single-frequency and narrow-linewidth lasers
For coherent experiments where linewidth, coherence length, and frequency stability matter more than raw output power.
