Heres a youtube video of the laser sound. Definitions:

T[f_, mf_, M_] := SawtoothWave[f t + M/(mf + .001)*SawtoothWave[mf*t]]

c = 1/3

r = 44100

A laser example (note you can press play repeatedly and have a starship battle):

LaserA = Table[ 4*Sin[55/(t + .0001) ]*T[22.5 t, 55/16, 55/8]*Exp[-t/(c/14)], {t, 0, 5 c, 1/r}]

ListPlay[LaserA, SampleRate -> 44100]

Example 2:

LaserB = Table[ 4*Sin[55/(t + .0001) ]*T[22.5 t, 0, 0]*Exp[-t/(c/13)], {t, 0, 8 c, 1/r}]

ListPlay[LaserB, SampleRate -> 44100]

Example 3: laser with slower initial chirp

RelaxedLaser = Table[ 4*Sin[165/(t + .0001)]*T[44 t, 4, 8]*Exp[-t/(c/20)], {t, 0, 8 c, 1/r}]
