Requirements to the modern navigation equipment of aircraft landing systems are very severe: equipment must be reliable, it has to efficiently make provision for the aircraft landing approach at any time of day or night including severe weather conditions and, what is not insignificant, not impair the pilots’ health. Developers of a new laser three-color navigation system managed to combine all these advantages thanrs to the usage of a new generation of electron-pumped semiconductor lasers – laser cathode-ray tubes (CRT).
