Paper Abstract
A strip Volume Bragg Grating (VBG) locked 64 emitter diode laser array’s center wavelength shift of each emitter
according to VBG’s local temperature is experimentally studied, which is consistent well with thermal imaging
temperature distribution, Finite element analysis (FEA) is then used to study strip and large area VBG’s temperature
gradients, we find even with minute heat deposition, due to PTR glass’s low heat conductivity, tens degrees temperature
gradient could easily be built, we suggest it may be partially respond for stack’s poor spectra narrowing performance
compared to single laser diode and diode array. Finally, some measures are further suggested to alleviate the effect.
