# LIDT Pulse-Scaling calculator

Scale a damage threshold from one pulse width to another via √τ.

Category: [Laser & Ultrafast](https://aperioptic.com/calculators)

Formula: `F2 = F1 · √(τ2/τ1)`

## Inputs

| Input | Parameter | Unit | Default |
| --- | --- | --- | --- |
| Spec fluence (J/cm²) | `F1` |  | 10 |
| Spec τ | `t1` | ns | 10 |
| Your τ | `t2` | ns | 0.00015 |

## Result with the default inputs

- Scaled LIDT: 0.0387 J/cm²

Open it with your own values: put each input in the address as a parameter, for example [`/calculators/lidt-pulse-scaling?F1=10`](https://aperioptic.com/calculators/lidt-pulse-scaling?F1=10). A unit other than the listed one goes in `<parameter>_unit`.
