Abstract

motor a laser. são providos projetos e técnicas para construir e operar lasers de pulsos de femtossegundos. um exemplo de um motor a laser inclui um oscilador que gera e emite um feixe de pulsos de semente de femtossegundos, um compressor-extensor que estende a duração dos pulsos de semente e um amplificador que recebe os pulsos de semente estendidos, amplifica uma amplitude de pulsos de semente estendidos selecionados para criar pulsos estendidos amplificados, e emite um feixe de laser de pulsos estendidos amplificados de volta para o compressor-extensor, que comprime sua duração e emite um feixe de laser de pulsos de femtossegundos. o amplificador inclui um controlador de dispesão que compensa uma dispesão dos pulsos estendidos amplificados, tornando a taxa de repetição do laser ajustável entre procedimentos ou de acordo com a velocidade de varredura. o motor a laser pode ser compacto com um trajeto óptico total menor do que 500 metros e ter um baixo número de elementos ópticos, p. ex., menos do que 50.
