By inserting a diffractive optical element (DOE) into the laser resonator, the output of the laser is converted from a single Gaussian mode or a near-Gaussian mode to a super-Gaussian mode output, thereby homogenizing the output spot and avoiding the middle strong and surrounding weak, or annular distribution etc. uneven condition.

The conventional outputs of Q-switched lasers and sub-nanosecond lasers are linearly polarized light. Linearly polarized light has different optical properties in different directions, which is not conducive to stable and consistent treatment and harmful on laser protection (such as the change of the shape and intensity of the light spot with the rotation of the arm and handpiece, etc.). At the output end, the linearly polarized light is restored to circularly polarized light by an optical element, which is beneficial to eliminate these adverse effects.

Homogeneous flat-top beam profile is free of hot spots. Consistent depth of penetration for predictable results.

In the Q switch mode, the IGBT discharge is used to control the xenon lamp to emit light. The Q switch is only turned on after the xenon lamp is extinguished, so that the output light is only a Q-switched laser with high peak power (commonly known as dynamic light), and eliminates the output of static light, which is conventional relaxation oscillation laser with the ineffective ness and thermal response to pigments. This way improves the therapeutic effect, reduces side effects, and improves the laser efficiency, low-carbon energy saving (about 26% energy saving), and is conducive to the continuous operation of the equipment and prolongs the lifespan

Integrated design of laser and optical transmission system (light guide arm, handle, etc.), integrated optimization, so as to achieve the optimal system (beam quality, spot uniformity, energy stability, lifespan, etc.).
