본 논문에서는 단파장 영역인 1018 nm에서 최고 출력 626 W를 가진 고출력 이터븀(ytterbium, Yb) 첨가 광섬유 레이저에 대해 보고한다. Yb 광섬유 레이저에서 이득률이 낮은 단파장 영역인 1018 nm에서 레이저를 발진시키기 위한 조건을 이론적으로 조사해보고, 광섬유 끝 단단면 조건에 따른 되먹임 신호를 측정하여 안정적인 레이저 발진 조건에 대하여 연구하였다. 그 결과를 바탕으로 제작한 단일 공진기 구조의 Yb 광섬유 레이저 시스템으로부터 729 W의 펌프 출력에서 최고 출력 626 W의 1018 nm 파장 레이저 출력을 안정적으로 얻을 수 있었으며 그때 기울기 효율은 86.6%로 측정되었다. 본 연구에서 얻은 1018 nm 파장의 Yb 광섬유 레이저 결과는 지금까지 국내에서 보고된 1030 nm 이하 단파장에서 발진된 Yb 광섬유 레이저 출력 중 가장 높은 출력이며, 세계적으로도 상용 Yb 광섬유와 광부품을 사용한 결과 중 가장 높은 출력에 해당된다. 그리고 향후 더 높은 출력을 얻기 위한 방법에 대해 논의하고자 한다.
