SOLAR LS produces a widest range of standard solid-state lasers. However, for solving some particular issues, our Users often need unique systems adapted for the requirements of certain experiments or specific tasks.

For more than 25 years of work in the international photonics market SOLAR LS has acquired huge experience in developing such systems.

We are able to promptly design customised systems of any complexity thanks to the following facts:

  • First, we have a wide range of standard lasers and non-linear converters which can supplement each other thus creating different configurations.
  • Second, we already have a lot of systems as well as their parts and units designed during many years of performing development projects.
  • Third, we have the group of highly skilled and qualified specialists in the field of laser physics, mechanics and electronics professionally dealing with development of such systems.

When designing such systems, we take into account the Customers requirements from the point of view of spatial configuration, laser radiation parameters and possibilities to control the whole system or its separate units.

In the course of a laser system development, we will offer and coordinate with you the optimum solution having preliminarily clarified your wishes concerning the following aspects:

Relative position of the laser system parts:

  • linear;
  • coplanar;
  • several-leveled.

Peculiarities of laser radiation extraction beyond the laser system:

  • multi-channel radiation output;
  • extraction of different wavelengths in one channel.

Requirements to automation:

  • manual control;
  • PC control.

Laser system mounting frame:

  • arrangement of the laser system parts on a honeycomb breadboard;
  • arrangement of the laser system parts on a specially developed mounting frame.

Requirement of the optical system for forming laser radiation:

  • telescopes and objectives;
  • fiber output;
  • radiation extraction via an articulated arm.

Supplementing the laser system with additional accessories:

  • power meters and laser radiation attenuators;
  • built-in systems of laser radiation wavelength measurement and control;
  • auxiliary optical components and their holders;
  • optical tables;
  • protective goggles, etc.

Please, contact us to create your unique laser system.

The laser systems developed and offered by SOLAR LS can provide at the output a number of fixed wavelengths as well as tuneable radiation in different spectral ranges.

Combination of various laser and non-linear converters based on advanced active media and non-linear crystals allows us to realise laser systems providing continuous wavelength tuning within the range from 0.2 m to 20 m.

When designing a laser system meeting your specific requirements we, as a rule, build it using the following basic modules:

  • Nd:YAG lasers with harmonic generators;
  • Al2O3:Ti3+ (Ti:Sapphire) lasers with harmonic generators;
  • , , , AgGaSe2, ZGP-based OPOs with harmonic generators;
  • , , -based sum frequency generators;
  • CdSe-based difference frequency generators.

Depending on the requirements to the laser system, as parts of the laser system can be used both our standard models and specially developed ones.

Wavelength tuning is performed either manually by micrometric screws or by actuators via PC.

For real-time control over the operating wavelength (including in the wavelength range of 320 m) the laser system can be supplemented with an original compact laser wavelength meter.

In this section you can get acquainted with some of the laser systems developed by SOLAR LS under orders of our Customers. Feel free to contact us for more information about the systems we designed, their detailed specifications and applications.

Inform us of your requirements and we will offer you the best solution for your tasks within the shortest time.
