Description
Technical field
The present invention relates to laser therapeutic apparantus field more particularly to a kind of portable electro-optical Q-switch laser skin therapeutic equipments.
Background technique
With the development of laser technology, a brand-new application branch of learning --- laser medicine is gradually formed, the uniqueness of laser
Advantage solves traditional medicine indeterminable many problems in basic research and clinical application, causes domestic and international medicine
The attention on boundary.
In medical skin therapy field, adjust Q (Q value -- be defined as, the gross energy of storage and intracavitary list intracavitary in laser resonance
Position time loss the ratio between energy) laser tatoo, spot, striae of pregnancy, too the moles such as field spot, whelk scar, pore refining,
Using more and more in the treatment such as tiny wrinkle of skin and tender skin, and the significant effect in most for the treatment of.At present
There are mainly two types of Q-switch laser therapeutic equipments for industry: one is the vertical therapeutic equipment for carrying out beam Propagation using light-conducting arm, another kind is
Portable (i.e. desk-top) therapeutic equipment being placed in using laser in laser therapy handpiece.Both therapeutic equipments respectively have advantage and disadvantage:
Vertical to have energy big, relatively light advantage is treated in light-conducting arm output, but beam Propagation efficiency is lower, and instrument is cumbersome,
Be inconvenient to move and maintenance；Although portable energy is relatively low, laser pulse is narrow, and peak power is high, be moved easily with
Operation.Due to its advantage, portable Q-switch laser therapeutic equipment is in the treatment of skin disease using more and more.
But for portable Q-switch laser therapeutic equipment currently on the market, it is all made of saturable absorber (at present usually
Using Cr+4:YAG) it is used as adjusting Q crystal, this is a kind of passive Q-adjusted mode, compared to using electro-optical Q-switching laser (electric light tune
Q-- utilizes the electrooptic effect of crystal, and a step-like voltage is added on crystal, the reflection loss of photon, first stage in adjusting cavity
It is on crystal plus λ/2 V, polarised light passes through the equal two-beam of the amplitude for being decomposed into when KDP crystal and vibrating along X and Y-direction, and two
The direction of vibration of Shu Guang is vertical, and frequency is identical, and when propagating in same direction, the rule mark of synthesis is determined by the phase difference of two light
Fixed, as Φ=π, two-beam synthesizes a line polarisation, its direction of vibration is rotated by 90 ° with respect to the former direction of vibration of incident light.
Because of P1//P2, from crystal come out light cannot be reflected away by P2 by P2, so light cannot it is intracavitary come back propagation
Form oscillation.The loss that this is equivalent to intracavitary photon is very big, and Q value is very high, state of referred to as " closing the door ".Second stage: pulse form
At the stage -- Q-switch fully opens, when the inverted population of operation material reaches maximum value in the first stage, crystal of decorporating suddenly
On voltage, at this moment crystal has restored original state again, and light is vibrated in intracavitary formation.) actively Q-switched mode for, due to
Q-switch is started by laser emission itself, and high-voltage high-speed electric light driver or radio-frequency modulator are not needed, and is set although having
Simple advantage is counted, small in size, cost is relatively low；But outside control performance accuracy is low, exports energy compared with electric-optically Q-switched laser
