a, b, Schemes A and B to generate counter-propagating Stokes and pump Bessel light bullets with opposite angular dispersion.

They have demonstrated the advantages of the B2-SRS technique for deeper tissue 3D chemical imaging on fresh porcine brain tissue. The Bessel light bullet generated in B2-SRS has shown a remarkable scattering resilience feature in turbid media, B2-SRS gives a>2-fold improvement in penetration depth in brain imaging compared to conventional SRS imaging.
