Laser Pulse Config.  
Pulse duration (FWHM, Intensity) : fs     Pulse Intensity $I_0$ : W/$\mbox{cm}^2$    
normalize Vector Potential $a_0$ = $\displaystyle\sqrt{\frac{2e^2\lambda_0^2I_0}{\pi m_e^2c^5}} = 0.855\times 10^{-9}\sqrt{I_0\mbox[W/cm]^2}\lambda_0[\mu\mbox{m}]$ = (dimensionless),    
Transvese Electrical Field = $\displaystyle 3.21\displaystyle\frac{a_0}{\lambda_0 [\mu\mbox{m}]}\displaystyle\frac{\mbox{TVolts}}{\mbox{m}}$ = $\displaystyle\frac{\mbox{TVolts}}{\mbox{m}$
Given $I(t)=\displaystyle\frac{1}{\sigma \sqrt{\pi}}\exp\left(-\displaystyle\frac{(x-\mu)^2}{2\sigma^2}\right)$, FWHM = $2\sqrt{2\ln 2}\sigma \simeq 2.35 \sigma$.
Gaussian Beam: $ I(r) = \displaystyle\frac{2P_0}{\piw^2}\exp\left(-\displaystyle\frac{2r^2}{w^2}\right)$, FWHM = $2.5(w/2)$ = 1.175 $w$.
Temporal Gaussian profile definition in OSIRIS : $\displaystyle\exp\left( - \frac{2(\mbox{x-lon_x0})^2}{\mbox{lon_duration}^2}\right)$ if $|\mbox{x-lon_x0}| < \mbox{lon_range}$, and $0.0$ otherwise. $I(x)\approx\displaystyle\exp\left( - \frac{2(\mbox{x-lon_x0})^2}{\mbox{lon_duration}^2}\right)$
Time and Space Config.  
laser Wavelength $\lambda_0$ :   nm   laser frequency $\omega_0$ : THz
set plasma frequency $\omega_p =$ laser frequency $\omega_0$, we have $n_0$ : ($\displaystyle{1/\mbox{cm}^3}$)
normalized dt, 1/$\omega_0$ : fs
normalized dL, c/$\omega_0$ : nm
x1 min : um,       x1 max : um,       grid Length $dx_1$ = nm
x2 min : um,       x2 max : um,       grid Length $dx_2$ = nm
Courant-Levy criterion: dt < dL/c, dL = $\displaystyle\frac{1}{\sqrt{\frac{1}{dx_1^2}+\frac{1}{dx_2^2}}}$ = nm.   dt = fs      
dt in OSIRIS = times Courant-Levy criterion = fs
