simulating intensity modulated point source

Hi,
I am working on a project on Diffuse Optical Tomography. We are using COMSOL to simulate lasers irradiating a biological tissue with certain vales of scattering and absorption coefficients. Till now, we had used a constant point source by putting 'u_test' in the weak coefficient of point settings. But now, we want to modulate the intensity(or amplitude) of this point source sinusoidally. I am not able to find any ideas anywhere. Please Help, very urgent.

Hello. I have met the same problem. I tried to simulate a point soure. But it emits sephere light. I want it to emit line light. Have you sloved the problem?How did you do that?
