EXTREMELY HAPPY NEW YEAR !! from Azurlight

posted in: Allgemein | 0

The company was created in 2010, the year when it won the « Photon d’or » (Golden photon) award for its blue fiber laser (488 nm 2 W). The company was the first and still is the only one to propose that kind of power level, and so the name « Azurlight Systems » was born. Azurlight Systems has, over the last 10 years, expanded its product range in the IR, the visible and UV wavelength.
Every year, new products are designed. Our latest achievement is the 130 W 1064 nm fiber laser with the lowest intensity noise on the market.
In 2020, we will do our best, as always, to answer your demands and several exciting innovations are coming! Keep in touch!

LIGHT AS A METROLOGY DEVICE

HIGH PERFORMANCES INSTRUMENTATION BASED ON LASER INTERFEROMETRY

INTERFEROMETRY PRINCIPLE

  • Interferometric technics are used to measure displacements or pertubations on an optical path. In an interferometer, a single frequency light source is split into two beams. Each of the two beams takes a different trajectory and are then recombined. At this point, interferences are created. Those provide different information and data on the optical path.

HIGH PERFORMANCES LASER INTERFEROMETRY APPLICATIONS

  • On a large scale, laser interferometry is used to detect and identify gravitational waves. Large-scale Michelson interferometers like LIGO (USA) and VIRGO (France, Italy) consist of large arms each several kilometers long in which the laser can spread. The disturbance created by gravitational waves applies a very slight change in the length of an arm. That’s why the longer the arms of the interferometer, the better the sensitivity of the system to vibrations. The interferences created, allow the identification of the gravitational waves.
  • On a more industrial scale, the principle of interferometry is used for surface control, accurate positioning, or Laser Doppler Velocimetry. The latter application principle is that well-controlled size particles cross a determined interference pattern and a camera records their speed. One can then deduct the speed of the flow.

AZURLIGHT SYSTEMS LASERS BENEFITS

In order to reach high performances, one need a high performance laser:

  • It must have a high power to give the best resolution possible. Indeed, the more power there is, the better the sharpness of the interference pattern. Therefore, for the example of gravitational waves, the analysis of the disturbance created will be improved.
  • Its intensity noise must be ultra-low to detect weak disturbances.
  • Moreover, the stability of the laser in terms of pointing and frequency is major! It takes a high coherence length since the systems extend kilometers.

ACTIVE NOISE REDUCTION SYSTEM LATEST ACHIEVEMENT

The Azurlight R&D team strikes again! This time, they achieved to combine the lowest intensity noise with the highest output power for single-frequency lasers.

Since its foundation, the Azurlight Systems R&D team has been accumulating extensive knowledge of this optical phenomenon. Initially, the team developed its own measurement system to push the detection limit and is now able to compensate actively this perturbation. Applications in atomic physics or gravitational wave detection will benefit from this groundbreaking improvement.

Today, our products stand on a new step, the highest one of the podium! The active noise reduction system is available for the 130 W system and soon for all our infrared series. Ask us for more information on this innovative feature! Read more: active noise reduction system

GET TO KNOW US BETTER

We love to learn about our applications of our systems. What a satisfaction to see that our very first 10 W 532 nm green laser is still in very good shape! Within the Néel Institute in Grenoble, the laser is mounted on an optical setup rotating at 1 turn/s! This is clear proof of the reliability of our systems under extreme conditions.

Mr. Gibert, in charge of this experimental setup, reports:
« The 10 W 532 nm fiber laser from Azurlight Systems is embedded on a 1.5 m diameter rotating table levitating on air cushion and spinning at 60 rpm. It is mounted there together with an optical cryostat named CryoLEM (Cryogenic Lagrangian Exploration Module) equipped with 8 optical ports. This setup was designed to study Deuterium microparticles movement transported by an ultracold quantum fluid (superfluid Helium at 1K).
The rotation of the experiment generates quantum vortexes and those affect these particle dynamics. This is actively studied thanks to the illumination of those microparticles by the interference pattern generated by the Azurlight laser. »
