  The multiple lobes of high order Hermite-Gaussian (HG) laser modes differ in
terms of shape, size, and optical energy distribution. Here, we introduce a
generic numerical method that redistributes optical energy among the lobes of
high order HG modes such that all the identical low intense lobes become both
moderate or high intense lobes and vice-versa, in a controlled manner. Further,
the modes which consist of only two types of intensity distribution among its
multiple lobes are transformed together into all high intense lobes.
Furthermore, in some cases, moderate intense lobes together with high intense
lobes become high intense lobes, and moderate intense lobes together with low
intense lobes become high intense lobes. Such controlled modulation of optical
energy may offer efficient and selective utilization of each lobe of HG modes
in most applications like particle manipulation, optical lithography, and the
method can be used in other fields like nonlinear frequency conversion and
shaping ultrafast optical pulses.
