History

Single-beam infra-red spectrophotometer (1955).

Small Raman spectrophotometer.

The knowledge gathered in the field of spectrophotometer and equipment of the laboratories helped significantly in the design of a first Czechoslovak gas laser put into operation in October 1963. It was only half a year after startig of the project and two years after the first gas laser in the world. Research in the field of solid-state lasers started as well.

Ing. František Petrů, head of the team developing gas lasers.

Years 1965 and 1966 were devoted to work on gas lasers with higher output power.

Gas laser 2000 K with the output power 50 mW was designed for the Raman spectroscopy and produced in the years 1966-70 in the state company Meopta Přerov.

Properties of the He-Ne laser 2000 K radiation were used in the Raman spectrophotometer, which was designed in 1967.

The first experimental model of the interferometric system for length measurements with the 800 K laser was designed and tested in 1967, at the time when the first single-frequency He-Ne laser was being developed especially as a laser source for the laser interferometry.

In the year 1969 works of the highly stable single-frequency He-Ne laser LA 1000 were finished. This created a basis for much broader application of laser radiation in measuring technology.

The Laser interferometer represented another step tpwards an universal length measuring system.

The first model of the universal length measuring system.

The core of the system was supplemented by other units as a printer, x-y plotter and an automatic correction unit for the compensation of the refractive index of air. The company Metra Blansko included the system into their production line as a complex equipment for laboratories of industrial metrology in mechanical engineering.
