Ширина линии испускания импульсного ВКР-лазера на KGd(WO4)2 экспериментально проанализирована для различных конфигураций резонаторов ВКР-лазера и лазера накачки: при узкой и широкой ширине линии испускания лазера накачки; в присутствии и отсутствии элементов, сужающих линию испускания, в резонаторе ВКР-лазера; в присутствии и отсутствии затравочного излучения в резонаторе ВКР-лазера. Объяснены преимущества использования лазера накачки с узкой шириной линии испускания в комбинации с элементами, сужающими линию испускания в резонаторе ВКР-лазера, для эффективного сужения ширины линии ВКР-излучения. Продемонстрированы импульсы с пиковой мощностью 20 кВт на длине волны 1156 нм с шириной линии излучения 0,43 см-1 в ВКР-лазере на кристалле KGW с затравочным излучением.

The linewidth of a KGd(WO4)2 pulsed Raman laser is analysed experimentally for different configurations of the Raman and pump resonators: with narrow and broadband pump emission profiles, with and without linewidth narrowing elements in the Raman laser resonator, with and without injection seeding into the Raman cavity. The benefits of a narrow linewidth pump source in combination with linewidth narrowing elements in the Raman laser cavity for the efficient linewidth narrowing of the Raman emission are explained. 20 kW peak-power pulses at 1156 nm with 0,43 cm -1 emission linewidth are demonstrated from an injection seeded KGW Raman laser.
