The Laser is continuously activated or pulsed (100 µs) for various frequencies, the SLD/LED is
continuous or 50% duty cycle for various frequencies.
The Laser is a single device, where the SLD/LED uses 19 devices.
The use of SLD/LED in phototherapy is gaining acceptance as the power of SLD/LED’s is increasing,
thus reducing the treatment time for therapy on larger areas. It has been proposed that coherence is
not a significant parameter in phototherapy treatments and because of the rapid change in SLD/LED
technology and their therapeutic use, regular reviews of the literature are recommended to compare
these treatment methods.
