1皮秒 = 10 -12 秒 或 1/1,000,000,000,000秒
1 picosecond = 10 -12 second or 1/1,000,000,000,000 second

B：Tim Sir，現在人人都說做「皮秒」？到
底什麼是「皮秒」？ 但是，只有蜂巢鏡可為每小束針狀激光產生平
均的能量，而微透鏡是做不到的。 B: Hi Timothy, everyone is now talking about
“picosecond laser”, so what actually is
"picosecond laser"?
T：皮秒激光在醫學美容界別而言，是一個擁有
最短脈衝時間的激光系統，主要用作解決色斑
問題。較短的脈衝時間可讓足夠能量更快地傳
達至皮膚更深層，同時卻不會破壞皮膚表層。 B：PicoWay這部皮秒激光儀器的原理是怎樣
的？有什麼特點？ T: Picosecond laser in the field of medical
aesthetics is a laser system with the shortest
pulse duration mainly for resolving pigmentation
problems. Shorter pulse duration allows us to
deliver enough energy very quickly into deeper
layer of our skin without damaging the surface
layer of our skin.
B：皮秒激光的「脈衝時間」與「波長」之間
有什麼關係嗎？何者較重要？
T：皮秒激光的「脈衝時間」與「波長」同樣
重要。短脈衝時間介乎10 -12 秒，就可被定義為
皮秒激光(ps)。脈衝時間非常短，令接觸皮膚
的能量亦降至最低，能量亦並未有加熱組織。
高強度的能量會錘擊組織內的色斑，稱為「光
機械效應」。
至於皮秒激光的波長，則決定激光能量可以到
達皮膚的深度。較短的波長，如532nm波長，
就最好用來處理表層色斑。而較長的波長，即
1064nm就針對皮膚組織深層的色斑。
B：坊間很多皮秒療程都聲稱配有「蜂巢鏡」，
到底什麼是蜂巢鏡？有什麼作用？
T：市場上的蜂巢鏡或微透鏡可將一整束激光
分段並轉化為細小的針狀激光。當這些轉化了
的激光到達一個焦點，能量會變得極高，焦點
上的皮膚組織會氣化。這就是「激光誘導光學
分解(LIOB)」，會造成細小的傷口，從而激發
自身的自然修復機制，刺激膠原蛋白再生，緊
緻毛孔，令皮膚再生。
T：PicoWay有助減少色素沉澱與紋身色素，
也可幫助皮膚再生。
PicoWay的高能量峰值令它更有效和更安
全，450皮秒(ps)脈衝產生的光機械效應，比
其他低能量脈衝皮秒激光多4.5倍。PicoWay
用1064nm與532nm波長去針對深層與表層色
素沉澱。它也有效針對黑、藍、紅色的紋身色
素。新增的785nm波長更可有效針對較淺色的
紋身色素，如淺綠與淺藍。
PicoWay的Resolve探頭使用蜂巢鏡，並且得到
美國食品藥物管理局(FDA)臨床實證可使皮膚
再生。不少其他皮秒激光療程使用的蜂巢鏡其
實是沒有FDA認可的。
B: Is there any relation between the pulse
duration and wavelength of picosecond
laser? Which one is more important, pulse
duration or wavelength?
T: Both pulse duration and wavelength of
picosecond laser are equally as important. Short
pulse duration at range of 10 −12 second defines
the laser as picosecond laser (ps). The pulse
duration is so short that the energy which comes
into contact with the skin's surface is reduced
to the minimum. Further, such energy does not
act through heating up the tissue but instead,
the strong energy delivered behaves as acoustic
energy hammering the pigmentation into our
tissue. This is called the photo-mechanical effect.
As for the wavelength of picosecond laser, it
defines the depth of how far the laser energy can
penetrate into the skin. Shorter wavelength such
as 532nm is best for superficial pigmentation
while longer wavelength 1064nm could target
pigmentation in the deeper layer of our skin tissue.
B:
There are a lot of picosecond laser
treatments in the market claiming that they
are using “holographic lens”, so what is a
“holographic lens”? What is the function of
this lens?
T: Holographic lens or micro-lens in the market
can fractionate and convert a full laser light
beam into fine needles of laser light. When
these converted laser light travel to a focal
point, the energy is so high that the skin tissues
at the focal point would be evaporated. This is
called laser induced optical breakdown (LIOB),
which causes tiny injury that would trigger our
natural body repair mechanism leading to skin
rejuvenation - stimulated growth of collagen and
pores tightening.
However, only holographic can generate even
energy for each laser light needle while micro-
lens does not.
B: What is the working principle of the PicoWay
picosecond device? What are its features?
T: PicoWay can help to reduce pigmentation
and tattoo ink, as well as providing a solution
for skin rejuvenation.
The high peak power of PicoWay brings greater
efficacy and safety. Its 450ps pulse delivers 4.5
times more photo-mechanical effect than the
lower energy pulse of other picosecond lasers.
PicoWay employs 1064nm and 532nm for
targeting deep and superficial pigmentation. It
is also effective removing black, blue, red tattoo
ink. New additional 785nm wavelength could
also effectively target lighter tattoo ink such as
light green and light blue.
PicoWay Resolve mode with holographic lens
is clinically proven ( FDA approved ) for skin
rejuvenation by stimulating collagen generation
and wound healing effect. The result is skin
tightening and pore refinement.
