Mean and standard deviation values of surface roughness and damaged height (n=3)

Tip-power Ra (μm) Rz (μm)
Control 0.234±0.01041 1.08±0.045
PowerLINE-LP 0.249±0.001856b 1.05±0.095b
PowerLINE-MP 0.164±0.00802a,b 1.68±0.190a,b
PowerLINE-HP 0.185±0.00737a,b 2.19±0.26a,b

Values are presented as mean±standard deviation.

Ra, average surface roughness; Rz, damaged height; LP, low power; MP, medium power; HP, high power.

aStatistically significant difference from control (p<0.05). bStatistically significant difference between experiments (p<0.05).
