The laser pulse energy, water and hemoglobin absorb, so to penetrate the
organization deeper [18]. The laser frequency doubling technology output 532nm
green laser, ie, multiplier: the laser spot diameter of 2 ~ 6mm, the energy
density of ~ 12j/cm2. The director is carefully arranging the production
preparation of Laser Pointer .
Oxyhemoglobin in the blood vessels on the
wavelength of 532nm light absorption secondary to 585nm light, but you can
choose the 532nm wavelength laser pulse width appropriate for treatment of
vascular lesions. Because of its shallow penetration, and thus generally limited
to shallow vascular lesions treatment. In addition, the multiplier: the laser
can also be widely used in bleeding, hemangioma treatment and micro-surgery,
skin pigmentation variation caused by man-made tattoos, tattooing of lips, etc.
by the red dye particles also has a therapeutic effect [19]. Melanoma cells to
the absorption of the 532nm laser, coupled with the wavelength of the strong
scattering of skin tissue, radiation in the 532nm laser energy on the skin
confined to the skin, the epidermis. The customer asks the company to provide
some analysis data of Laser Pointer .
Q-switched technology, superficial
melanoma cell proliferation, such as coffee spot, age spots, freckles, etc. to
achieve a better therapeutic effect [20]. The solid-state lasers based on doped
solid materials such as glass, crystal or transparent ceramic lasers as the
working substance. Since the world's first laser invention, the solid-state
laser technology has made great development, mainly in three aspects: first,
continuous improvement of the working substance. Was first ruby laser, the
subsequent emergence of a neodymium glass and neodymium-doped yttrium aluminum
garnet laser, and now the neodymium-doped gallium gadolinium garnet laser. Also
reported that the emergence of new laser materials, ceramic-matrix. The second
is the improvement of the pump source. The production preparation of Laser
Pointer is of much importance.
Initial flash, and later developed into the
arc lights, high power laser diode pumped. Third, the changes in the structure
of the working substance. Rod structure from the initial development into a
slat-style, but also to the fiber structure. The development trend of the
solid-state lasers is the diversity of materials and devices, including the
seeking of new material, of the new wavelength and wavelength tunable laser
conversion efficiency, increase output power, beam quality, compressed pulse
width, improve reliability and extension of working life.
