26. The 594 nm laser beam from a He-Ne laser was too weak to allow the measurement of the Glass constant. The value of R found by extrapolation is 1.9.
27. To avoid any residual Δn induced by the SB during optical alignment processes.
28. We have also checked the SB size near the output face by scanning a razor blade across the SB at a position ∼0.1 mm from the output face and monitored the signal intensity at the far field by a photodiode. The beam size of a SS deduced by this method is consistent with the value shown in Fig. 4.
