CW Lasers

CW Lasers

CW lasers or continuous wave lasers are designed to be on continuously and not pulsed.  Many DPSS lasers are designed for pulsed applications with higher peak energy.

For reference:

A millisecond (ms or msec) is one thousandth of a second.

A nanosecond (ns or nsec) is one billionth (10 -9) of a second.

A picosecond (ps) is one trillionth (10 -12 ) of a second or one millionth of a microsecond.

A femtosecond (fs) is one quadrillionth (10 -15 ) of a second

An attosecond is one quintillionth (10 -18 ) of a second.
