Table 1
The relationships between the pulse length of high power and LID of components.
| Laser pulse length | Damage mechanisms | Damage phenomena |
| Long pulse | Thermal absorption | Stress, strain, melting, and ablation | Continuous wave |
| Short pulse for ns level | Impact ionization | Micropits, debris |
| Extremely short pulse for ps level | Impact ionization | Crater, plasma, and crush |
| Ultrashort pulse for fs level | Multiphoton-assisted impact ionization | Crater, plasma, crush, and cracks |
