About Microjoules
A microjoule (µJ) is 10⁻⁶ J - the scale of precision laser ablation, ESD damage events, and individual LIDAR pulses. LASIK eye surgery delivers 0.5-2 µJ per pulse at 193 nm, ablating ~0.25 µm of corneal tissue per pulse. ESD events that destroy IC gates correspond to 1-1,000 µJ; the Human Body Model test discharges ~500 µJ at 2 kV. Q-switched microchip laser pulses for rangefinding are 1-100 µJ. The kinetic energy of a 1 mg grain of sand falling 10 cm is mgh ≈ 0.98 µJ. 1 µJ = 10⁻⁶ J.
About Nanojoules
A nanojoule (nJ) is 10⁻⁹ J - the scale of ultrashort laser pulses, flash memory write operations, and cellular ATP reserves. A Ti:sapphire laser oscillator produces pulses of 1-20 nJ at 80 MHz. Flash NAND programming costs ~1-10 nJ/bit written; a read is ~0.1 nJ/bit. The total ATP energy stored in a single red blood cell is ~1-5 nJ. The kinetic energy of a 1 µg particle at 1.4 m/s is ~1 nJ, illustrating that nanojoules describe real nanoscale mechanical events. 1 nJ = 10⁻⁹ J.
