A HeNe laser tube is used as the source of coherent frequency stabilized radiation. The two mantle laser tube design gives the product a long lifespan. The laser tube is filled with a mixture of isotopes He3, Ne20 and Ne22. This results in a well defined power maximum in the middle of the laser line. This maximum is used as a reference point for laser frequency stabilizing servo loop. The laser frequency stability and reproductibility achieved is 2.10-8 and is checked for each laser. Thanks to this new solution, high resistance to possible frequency instability caused by reflections of laser radiation back to the laser has been obtained. The double mantle laser tube design facilitates a compact and solid construction of the laser head. The laser tube is temperature compensated. The LS 11.1 power supply is a separate unit. This is advantageous in special applications such as the positioning of precise X-Y tables where minimizing of heat sources is required. The laser is a source of coherent radiation with wavelength 633 nm and power less than 1 mW. It belongs to safety class 2 of laser products. It is safe to use and no special safety precautions are necessary.
Laser is delivered with built-in or external receiver.
