Standoff Methods for the Detection of Threat Agents: A Review of Several Promising Laser-Based Techniques

Figure 7

Fraction of molecules transferred into state as a function of the delay between the pump and Stokes pulses. This calculation was performed with Gaussian laser pulses with a full width at half max = 62 ps and  rad/s (area = 20 radians). The insets at the top indicate the relative timing of the pulses. The violet curve represents . The blue curve represents .
