Pulse width & energy
Why the true picosecond model is priced higher
The picosecond model delivers its energy in a much shorter pulse (about 10–17× shorter duration). Its lower pulse energy therefore does not mean lower instantaneous power. Producing and maintaining these ultrashort pulses requires more demanding laser engineering, which contributes to the higher price.
| Specification | Q4781 True Picosecond | Q4780 Pro Q-Switched |
|---|---|---|
| Pulse duration | 350–500 ps | 5–6 ns |
| Same unit: ns | 0.35–0.50 ns | 5–6 ns |
| Pulse energy | 500 mJ | 1200 mJ |
| Estimated pulse power* | 1.00–1.43 GW | 0.20–0.24 GW |
*Pulse energy ÷ pulse duration, assuming both specifications are achieved together. Actual peak power depends on pulse shape. Values are based on supplier specifications.
