Laser Waves in Postage Stamp

Oct 31, 2013

On Saturday, February 23, Lithuania Post will release a new postage stamp from the series “Science Achievements”. The stamp is dedicated to the laser industry.

The stamp designed by the artist Evelina Paukštytė features laser waves. The stamp will be issued in the edition of 80 000 copies with the nominal value of LTL 1.35.

Along with the stamp, the first day cover and sheet will be issued. On Saturday, in Vilnius Main Post, all postal correspondence paid by the new stamp will be marked by the first day cancellation.

A laser is a device that emits coherent light (identical wave length, phase, and polarization). Usually lasers emit parallel beams of monochromatic light (one wavelength).

Lasers are used in a variety of applications: science, medicine, industry, home, entertainment, and for military purposes.

In 1974, the barcode scanner was introduced. This was one of the first applications of the laser in daily life.

Scientific investigations conducted at Vilnius University and the Institute of Physics gave stimulus for the establishment of companies working in the area of laser technologies. Graduates of these education and science institutions wished to put their knowledge into practice. As a result, the companies established in the years 1985-1995 (still functioning) naturally took over scientific investigations. The demand for lasers has increased when the need to speed up production processes and improve efficiency has arisen.

Lithuanian laser companies receive the largest part of income from lasers produced for scientific investigations.

In the course of a year, Lithuania Post usually issues 25-30 postage stamps. Lithuania Post provides postal, courier, and financial intermediation services.
