Usually, it is thought that the lasing wavelength of a fgesl is locked at the bragg reflection wavelength of fiber grating ( fg ). owing to a relatively small dependence of the reflection spectrum of fg on ambient temperature ( - 0. 01nm / c ), the lasing wavelength of a fgesl is thought to behave more stable than that of a dfb - ld
由於fgesl的激射波長主要由光纖光柵（ fg ）的布拉格波長確定，因此選擇具有合適布拉格波長的fg就能使fgesl的激射波長處于預置波長處；同時，由於fg的布拉格波長受溫度變化的影響相對較小（ 0 . 01nm ） ，因此fgesl與dfb - ld相比具有更高的溫度穩定性。 -
