We have developed new high power red(664nm) laser diode and its system. This system has a wavelength of 664nm and a power output of 600mW(CW) to tissue. Its features are listed as follows;
1) Small, lightweight and portable.
·The size is 490 (W)×200 (H)×400 (D)mm and the weight is 20kg.
2) Easy to operate and reliable.
·Needs only 100VAC·3A power supply.
·The laser power is easily controled.
·The wavelength is stable (less than 1120.2nm).
·Coupled to quartz fiber for delivery of light.
3) Narrow FWHM (full width at half maximum).
·The full width at half maximum is less than 2nm.
4) Free of maintenance.
We beleive that this laser diode system and the support from medical specialists will contribute to the spread of photodynamic therapy.
