Ah I see, well we use the \. to group ciphers and \, as decimal point
(and we also say "comma", not "point" for decimals). ^^

Well, we can remedy this: according to Project Rho, the im****tant
formulas for lasers are:
Diffraction: RT =3D 0.61 * D * L / RL
where:
RT =3D beam radius at target (m)
D =3D distance from laser emitter to target (m)
L =3D wavelength of laser beam (m)
RL =3D radius of laser lens or reflector (m)
Beam intensity on target: BPT =3D BP/(=F0 * (D * tan(=E8/2))2)
where:
BPT =3D Beam intensity at target (megawatts per square meter)
BP =3D Beam Power at laser aperture (megawatts)
D =3D range to target (meters)
=E8 =3D Theta =3D Beam divergence angle (radians or degrees depending on
your Tan() function)
=F0 =3D Pi =3D 3.14159...
Hit probability: H =3D Cm/(78.54 * A2 * (Dk/150,000)4)
where:
H =3D maximum percent chance to hit target given light-speed lag(0.0 -
1.0)
Cm =3D target ****p's mean cross section (m2, for a purely convex object
this is 1/4 of the surface area)
A =3D target's acceleration (Gs)
Dk =3D range to target (km)
Hope that helps. ^^
