本論文提供了架構簡易、輸出窄光譜寬度黃光雷射的方式：使用2個VBG作v型光路的架構，產生窄光譜寬度的1064 nm與1342 nm作為基頻光，經由腔內非線性晶體BBO達到合頻的轉換，得到窄光譜寬度的593.5 nm黃光。其輸出的593.5 nm的半高寬不超過0.03 nm，最大輸出功率為2 mW。此593.5 nm的黃光在Fabry-Perot interferometer上可有單模的輸出。A simple scheme is proposed to generate narrow spectral width yellow laser output. Two volume Bragg gratings were aligned to form a v-shaped cavity to generate narrow spectral width 1064 nm and 1342 nm as fundamental waves. An intra-cavity BBO, non-linear crystal; was utilized to achieve sum frequency generation. We successfully generated narrow spectral width 593.5 nm output. The FWHM of 593.5 nm output spectrum was less than 0.03 nm, and single longitudinal mode was observed by a Fabry-Perot interferometer. The maximum 593.5 nm output power was 2mW.
