Which outcome increases when pulsed laser light interacts with a photorefractive crystal?

💡 Explanation

Self-focusing increases due to the photorefractive effect, because the laser induces a change in the crystal's refractive index, therefore the beam converges into itself forming a tighter spot, rather than undergoing simple linear refraction.
