lasers may be operated in continuous-wave mode
(with energy emitted as a constant beam), with low settings
and short application time, or in gated-pulse mode (with
energy emitted as a constant but interrupted beam, or
pulsed at specific intervals), with higher settings and longer
application time. Some diode lasers offer specific pulse
duration on–off time controls, allowing higher power to
be applied to the tissue for shorter periods of time, which
allow the tissues to cool adequately before receiving another
pulse of energy. This energy pattern limits accumulation of
heat, which decreases thermal collateral damage.
