Former world champions Laybourn-Juhl first killed off Yong Dae’s hopes of winning his first title of the day when they defeated him and his partner Ha Jung Eun 21-9, 21-16 in only 36 minutes.
It was a near perfect performance from the Danes who ended the tournament without dropping a singles game in five matches.
The win will surely give them a big confidence boost ahead of the All England which begins with the qualifiers on Tuesday.
Yong Dae’s day went from bad to worse when he failed to defend the men’s doubles crown.
Yong Dae and Jung Jae Sung, who had won the German Open twice in four years, were gunning for their third title and started as favourites against young Chinese pair Hong Wei-Shen Ye.
The unseeded underdogs, who had also knocked out second seeds Ko Sung Hyun-Yoo Yeon Seong in the semi-finals, appeared the fitter of the two pairs and Yong Dae’s exertion of playing in both the mixed and men’s doubles begin to tell.
In what was his 10th match in Germany, Yong Dae (left), battle gamely but in the end, Hong Weo-Shen Ye had the legs to carry them over the line, winning 21-19, 18-21, 21-19 in 65 minutes.
They were one of four Chinese winners in the tournament with Lin Dan and Li Xuerui winning the men’s and women’s singles event.
The fourth Chinese gold medallists were the women’s doubles pairing of Huan Xia-Tang Jinhua, who defeated South Koreans Jung Kyung Eun-Kim Ha Na 23-21, 21-13.
