We confirmed a pulse train at a high-repetition frequency of 1 GHz with a pulse repetition interval of 1 ns with pump power of 390 mW. Dispersion compensation optics are not needed in the cavity. After adding dispersion to obtained spectrum data as the phase term, we Fourier-transformed them to obtain a pulse waveform. For that waveform, we roughly estimated the full width at half maximum (FWHM) of the pulse broadened by the chirp effect caused by normal dispersion of YDBF. It was about 860 fs.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.141 No.12 （2021） 特集Ⅰ：電気・電子・情報関係学会東海支部連合大会 特集Ⅱ：研究会優秀論文本誌掲載ページ: 1500-1502 p原稿種別: 資料／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/141/12/141_1500/_article/-char/ja/
