Chan Pin permits the molecular laser application in dermatological department

Chan Pin follows molecular laser, it is pulse gas laser, be activationed when electric current is passed, the monochromatic that releases some wavelengh is smooth. Gas is mix by inert gase haloid mix and become, the inert gase of activation and haloid can form halide " r of e of m of i of E x c " the meaning that one word comes from the element that stimulate voice, suffer namely stimulating voice to follow an element is one kind stimulates voice 2 get together body " r of e of m of i of D of r of e of m of i of E x c " , group of these two words is synthesized " r of e of m of i of E x c " . The Chan Pin that applies at present allows molecular laser to basically have the following kinds: Argon fluorine (A r F) wavelengh of  of accurate element laser 193 n m ; Krypton fluorine (K r F) wavelengh of  of accurate element laser 248 n m ; Xenon is chloric (l of X e C) wavelengh of  of accurate element laser 308 n m ; Xenon fluorine (X e F) wavelengh of  of accurate element laser 351 n m . Laser of odd frequency accurate element is successive pulse gas laser, the smooth wavelengh that release is inside ultraviolet limits, pulse width is 10 ~ 30 n s , frequency is 0 ~ 35 H z , 4 kinds of Chan Pin allow the wavelengh of molecular laser to be aeriform particularity, the l of C of the e that it is X that is used at dermatological department at present follows molecular laser. l of X e C 2 get together body by inert gase xenon (the outerest have 8 electrons) and haloid chloric (the outerest have 7 electrons) composition. Haloid can pass accept 1 electron and other and atomic union, when should allowing an element to activation in electric current only, with be united in wedlock condition exists.

Laser of odd frequency accurate element and narrow an ultraviolet B (UVB) therapeutics and element of filling bone fat add ultraviolet A (PUVA) differ somewhat, respective characteristic is had in clinical curative effect and action mechanism respect. PUVA and narrow the comparison of wave UVB detailed sees watch 1 . Chan Pin follows molecular laser, namely target type UVB and narrow wave UVB compares the place that also has similarities and differences, detailed sees a table 2.

Express 1 . PUVA therapeutics and narrow the comparison of wave UVB therapeutics

Illuminant 400 n of 320 ~ agent of photosensitive of 313 n m needs 311 ~ of m photosensitive agent need not photosensitive agent curative effect is good better side effect is little fewer get used to a crowd the adult is applicable, children careful with adult, children all but irradiation time is long weak point
