In recent years, it has become clear that clusters cannot be narrowly conceptualized by focusing on their internal linkages but studies must also recognize their external dimension ( malmberg et al., 1996 ; bathelt, 2002 ; wolfe and gertler, 2004 )

We analyze the generation of external cavity frequency - doubling with knbo3 crystal theoretically. in order to get the second - order nonlinear conversion from 858nm to 429nm with knbo3, we use non - critical type - i phase - matching to avoid the walk - off effect the corresponding optimum focusing condition is as followings : double refraction parameter b = 0, focus parameter = 2. 84, optimum phase mismatch parameter = 0. 574. based on the theoretical analysis and numerical calculations, we obtain the ideal nonlinear conversion coefficient about 1. 45 % / w with crystal length of 7mm and 2. 07 % / w with crystal length of 10mm at the phase - matching temperature around 23. 50c
