single mode tuning 中文意思是什麼
single mode tuning
解釋
單模調諧-
Two - segment distributed feedback ( dfb ) semiconductor lasers can achieve tuning with single longitudinal mode in a certain wavelength range ; at the same time, its superiority also includes bistablity and wavelength conversion
其中,兩段式分佈反饋( distributedfeedback , dfb )半導體激光器可以在一定波長范圍內實現單縱模、可調諧工作;同時,它還具有雙穩、波長轉換等功能。 -
( 3 ) ln the fourth chapter of this dissertation, a tunable single - longitudinal - mode erbium doped fiber ring laser is achieved by using the very narrow bandpass characteristics of the self written grating formed in a section of erbium doped flber withoat undergoing pumping by stable standing wave in it. tl1e tunable laser ' s wavelength tuning range is 40nm, from l 523. 79llm to l563. 92nm
