For example. The diameter of the holes in piercing mode or the width of the kerfs depend of the wavelength of laser type. Greater wavelength imply greater diameter of holes or greater width of kerfs.

Probably you can find more information in the paper attached.

Combination of 532 nm and 1064 nm lasers are useful for Noninvasive skin rejuvenation and toning.

Actually, 532 nm Nd:YAG is a frequency-doubled green light of 1064 nm YAG:Nd laser. For this nonlinear optical (NLO) crystals are use. For NLO, most commonly available are potassium titanyl phosphate (KTP), Beta-Barium Borate (β-BaB2O4,BBO), Potassium Titanyl Arsenate (KTiOAsO4) crystal, which are used for frequency-double generations.

NLO Crystals are used for extending the laser spectrum from deep UV to far IR by various harmonic generations (SHG, THG), sum frequency generations (SFG), difference frequency generations (DFG) and optical parametric oscillators (OPO).
