In order to obtain the noncritical phase-matched property of BiB3O6(BIBO)crystal and improve its application,based on its thermo-optical dispersion formula,with the green light at 532nm as the pump light,the temperature tuning range,efficient nonlinear coefficient and acceptance parameter of BIBO in noncritical phase-matching are calculated accurately by means of MATLAB programs.When the matched angle θ=90°,the signal light can tunes within 0.65μm~3.0μm.When the signal light is at 670nm,the optimal phase-matched condition of difference frequency type Ⅱ(B)phase-matching is obtained:Tm=22.3℃,φ=35°,deff=1.904pm/V.The result is promising to be applied in the laser product in visible waveband,such as laser TV.
