Abstract :
Recently, microlaser arrays have been reported in which the active Fabry-Perot crystal supports numerous, independent gain elements. Here we discuss the design of linear microlaser arrays in Nd:YAG and Tm,Ho:YLF crystals (a.k.a. microbars) based on point-to-point imaging of the individual emitters of a l-cm-long diode-laser bar. Finite element analysis (FEA) has been applied to calculate the pump-induced temperature and facet displacement profiles that together determine the individual thermal waveguides in the microbar
