Investigating the possible thermal-induced nonlinearities in linseed, rose and chamomile oils using visible laser beam

الملخص EN

Possiblenonlinear optical characteristics in Linseed,Rose and Chamomile oils are investigated.

Large thermal-induced third order nonlinear refractive index,n2,(10-7- 10-6)cm2/W has been obtained in rose and chamomile oilsat532 nm continuous wave (cw) laser radiation.

Number of rings as well as the diameter of the outer most ring in each ring pattern is found to increased monotonically with increasing input power.Diffraction ring pattern resulted in Linseed oil by the simultaneous irradiation of the green andbluelight beamsat 532 nmand 473 nm respectively.
