Laser diode bar (LDB) are used increasingly often for many applications
but spectral bandwidth of LDB are generally approximately 2-4nm
far too wide for many demanding applications
e.g. spin-exchange optical pumping
terahertz generation
and lidar. External-cavity feedback can improve the spectral properties of LD or LDB. However
spectrum narrowing of LDB is more difficult than that of LD. Bar curvature (i.e. "smile") produced in the manufacturing process affects the spectrum narrowing greatly. By geometrical optics approach and ORIGIN software
smile which can be corrected by plano-convex cylindrical lens is simulated and the result is in good agreement with experiment. The selection of grating which is also a critical factor of spectrum narrowing will be stated. Finally
an external cavity consisting of fast axis collimator
two plano-convex cylindrical lens and a diffraction grating is used. The scheme is implemented on a 19-element LDB and yields 3-fold reduction in spectral linewidth under the situation that all optical elements in the system which are not optimized. Further
we use a slit in the experiment and analyze the spectrum narrowing of each element in LDB.
