Abstract
trata-se de um método e sistema para gerar pulsos de laser ultravioleta (uv) de femtossegundo (fs) que possibilita geração estável, robusta e opticamente eficiente de pulsos de laser fs de terceiro harmônico com o uso de cristais de quase casamento de fase periodicamente polarizados (ppqpmc) que têm diferentes números de camadas cristalinas periodicamente polarizadas que possibilitam um comprimento de conversão longo sem retroconversão e sem uma direção de casamento de fase especial. o laser uv de fs pode ter uma alta eficiência de conversão e pode ser adequado para operação de alta potência.
