Introduction, history of lasers and laser light production

WebEl término láser es un acrónimo que hace referencia a ‘light amplification by stimulated emission of radiation’, es decir, amplificación de luz por emisión estimulada de radiación. Es un dispositivo que utiliza la emisión inducida o estimulada para generar o amplificar la radiación electromagnética en el intervalo de la longitud de onda de la radiación óptica … WebUltrafast lasers. Ultrafast lasers are generally defined as lasers that produce pulses in the range of 5 fs to 100 ps (1 femtosecond = 10 −15 seconds). If a laser is able to oscillate in many longitudinal modes, such short pulses can be produced with the so-called mode-locking technique. lilly ects
