Types of lasers and their respective properties

Laser	Wavelength, nm	Penetration Depth	Vaporization	Coagulation	Cutting
APC	516	1–2 mm	–	++	+
KTP	532	0.8 mm	++	++	+
Diode	808	8–10 mm	+	++	+++
Nd:YAG	1060	4–6 mm	+++	+++	+
Thulium	1940	0.4 mm	++	++	+++
CO2	10,600	0.3 mm	+	–	+++

Plus and minus symbols refer to level of activity where −, refers to no activity and +++, refers to significant activity.
