📊 Laser Brightness Formula
B = P/(AΩ) = I/Ω = L
Where B is brightness, P is power, A is area, Ω is solid angle, I is intensity, L is radiance

💡 Tips & Information
- Laser brightness is a measure of power per unit area per unit solid angle
- Higher brightness indicates better beam quality and focusability
- Solid angle Ω = π(θ/2)² where θ is divergence angle
- Typical laser divergence: 0.1-10 mrad
- Brightness is conserved in optical systems
