@FFT FILE (LASER)

• If @FFT_SW (LASER) is true, open file to use the information inside. If @LASER_NUM is larger then one, record a set of data in one line.
• Is store as fft_file in the fortran code.

example

@FFT_FILE
"gaussFFT_w8000.inp"

Which mean if @FFT_SW (LASER) is true, simulator will open file named "gaussFFT_w8000.inp" to used information inside.
