Laser Brightness Calculator — Frequently Asked Questions
Q1 Why is laser brightness vastly higher than sunlight? ▾
Even modest laser power is confined to an extremely tiny cross-sectional area and an exceptionally narrow solid angle of divergence.
Q2 Can passive lenses increase laser brightness? ▾
No. The optical invariance theorem (conservation of etendue) dictates that brightness cannot be increased by any passive optical system.
