In this
paper, thermal effects in double-end pumped Nd:YVO4
laser crystal have been investigated. The analytical
expression for temperature distribution and thermo-optic
effects such as temperature-dependent change of refractive
index (dn/dT effect) and end effect have been calculated and
the results then applied to Nd:YVO4 crystal., Our
analytical model compared with exact numerical calculations
and good consistency has been shown.
Key
words:
Double
end pumped, thermo-optic effects, Nd:YVO4 crystal. |
