Please answer a question about the following article about Red:

Lasers emitting in the red region of the spectrum have been available since the invention of the ruby laser in 1960. In 1962 the red helium–neon laser was invented, and these two types of lasers were widely used in many scientific applications including holography, and in education. Red helium–neon lasers were used commercially in LaserDisc players. The use of red laser diodes became widespread with the commercial success of modern DVD players, which use a 660 nm laser diode technology. Today, red and red-orange laser diodes are widely available to the public in the form of extremely inexpensive laser pointers. Portable, high-powered versions are also available for various applications. More recently, 671 nm diode-pumped solid state (DPSS) lasers have been introduced to the market for all-DPSS laser display systems, particle image velocimetry, Raman spectroscopy, and holography.

When was the first ruby laser invented?
1960
Svara gärna på en fråga om följande artikel om Röd: Lasrar som avger i den röda regionen av spektrumet har funnits tillgängliga sedan uppfinningen av rubinlasern 1960. 1962 uppfanns den röda helium–neonlasern, och dessa två typer av lasrar användes flitigt i många vetenskapliga tillämpningar inklusive holografi, och inom utbildning. Röda helium–neonlasrar användes kommersiellt i LaserDisc-spelare. Användningen av röda laserdioder blev utbredd i och med de kommersiella framgångarna för moderna DVD-spelare, som använder en 660 nm laserdiodteknik. Idag är röda och rödorange laserdioder allmänt tillgängliga för allmänheten i form av extremt billiga laserpekare. Bärbara, högdrivna versioner finns även för olika applikationer. På senare tid har 671 nm diodpumpade solid state-lasrar (DPSS) introducerats på marknaden för all-DPSS laserskärmar, partikelbildvelocimetri, Ramanspektroskopi och holografi. När uppfanns den första rubinlasern?
