Types of Lasers

Sealed-tube CO2: Lower cost laser marking by surface discoloration. Suitable for plastics, paints, inks, ceramics and other nonmetallics.

Slab CO2: For deep surface modification of nonmetallics.

Diode-pumped Nd:YAG (DPSS): High quality beam and pulse stability. Narrow line width for small characters with deep material penetration.

Pulsed Nd:YAG:Very high peak pulsed power for deep engraving and wide line widths.

Frequency-tripled Nd:YAG: Ultraviolet wavelength produces narrowest line width for micromarking; optimum wavelength for several specialty materials.

Frequency-doubled Nd:YAG : Visible green wavelength for narrow line width, small-character marking; best for gold, many synthetics and plastics.

Q-switched Nd:YAG : High peak power, narrow pulse width for deep penetration marking/engraving. Optimum for most metallics and many nonmetallics.
