Our Product range

Stable Laser Systems specializes in the design and production of cavity stabilized lasers with narrow linewidth and ultra-stable drift characteristics.

Research laboratories realize many benefits by using SLS hardware and systems:

  • Prompt delivery of our precision engineered parts get experiments underway quickly. Off the shelf and custom components and systems are delivered with a modest increase upon the cavity fabrication lead time.
  • A multi-year warranty guarantees performance for years of trouble-free operation. If repair or retrofit is required, stock designs make changes fast and painless.
  • Full testing and precision characterization against comparable optical systems accompanies all systems. Such metrics provide peace of mind for new laboratories and new wavelength projects that need optical precision but not the overhead needed for such measurements.
  • Complete system documentation and user manuals are ideal for academic laboratories, multi-user facilities, and other laboratories with high user throughput.
  • Personal support and proven engineering of previous orders by our team of experienced engineers and scientists solidifies our reputation for delivering robust systems and keeping then operating for the long term.

Please contact us for any laser frequency stabilization or stable cavity request. We have many years of experience working with researchers and applied settings on narrow linewidth light sources for frequency standards, atomic physics, optical clocks, quantum computing, radar, interferometry, metrology, precision spectroscopy and more.

Custom systems and more

At Stable Laser Systems, our strength in laser stabilization has produced a range of other products. Capitalizing upon our expertise in optical cavity design, mounting, and thermal/mechanical isolation, we have also delivered custom systems and components for precision laser control and optical cavity applications.

Integrated Stabilized Laser Systems : SLS-INT-1550-100-3

This turnkey 3Hz linewidth stabilized laser offers excellent stability in a convenient rackmount box. We've integrated a high-finesse Fabry-Perot cavity, a temperature-controlled vacuum housing, vacuum pump, optics, input laser, and control electronics into a 3U high rackmount box, while maintaining the frequency stability for which our products are known. With a frequency noise linear spectral density of 1Hz/√Hz, this system is suitable for applications such as microwave generation and laser radar. Once the laser has been tuned to be coincident with the cavity frequency, a single-switch lock function engages the loop filter to stabilize the laser. An easy-to-read front panel displays laser current and temperature, cavity temperature, reflected power from the cavity, and loop filter & vacuum parameters, with analog outputs for transmitted cavity power, error signal, and ramp sync signal. A fiber pigtail output and monitor panel software for laser control make the system easy to integrate and use.

Everything about this integrated frequency stabilized laser has been designed to deliver the best performance in the most convenient way, from the low power consumption and battery backup to the onboard display. We put all of our experience into each system so that you can spend your time on your experiments, not your equipment. Our systems give you the frequency you need – guaranteed.

  • Full specification
  • Auto-lock is in development to eliminate manual tuning of the laser to the cavity frequency. Should the unit be bumped or jarred, automatic re-lock will engage to re-stabilize the laser.
  • The system will arrive aligned and under vacuum. The ion pump is equipped with battery backup to minimize the need for additional pumps after shipping or movement of the system.
  • A 1Hz linewidth system is available upon request in a 5U high rackmount box.

Breadboard Stabilized Laser Systems : SLS-1550-200-1

Our turnkey laser systems are the first of their kind in the field. They allow you to get a high performance frequency stabilized laser up and running in your lab quickly. With a quality high stability laser at its core, each system boasts a fully characterized ATFilms cavity mounted in a perfectly matched vacuum housing that is thermally controlled and monitored. Vibration isolation ensures rock-solid frequency stability. A fiber pigtail output and monitor panel software for laser control make the system easy to integrate and use. Our standard systems offer a stabilized laser linewidth of 1 Hz or better, with less than 30 kHz of daily drift at room temperature. Each system we ship has the thermal expansion of the cavity mapped out about the zero expansion temperature, to minimize the frequency drift of the laser. We can also custom design a system to your exact needs, at wavelengths ranging from the visible through the near-IR.

Monitor outputs:
PDH Error signal, Reflected power from the cavity, Transmitted power from the cavity with camera image, Vacuum pressure, Vacuum housing temperature
