Description
Technical field the utility model relates to a kind of frequency-doubling crystal of switched laser device to change the device of its output wavelength, especially at the quick switching between two frequencys multiplication, frequency tripling and laser of quadruple wavelength.
Background technology is present, and people often adopt the frequency multiplication tuner in order to change the output frequency of laser.It is made of frequency-doubling crystal that is provided with on the laser output optical axis or frequency multiplication module.During use, the laser of the specific wavelength of laser output is tuned to selected optical maser wavelength and uses for the back after frequency-doubling crystal or frequency multiplication module.But this frequency multiplication tuner exists the fixing deficiency of optical maser wavelength of output, if change the output of laser freuqency doubling, then needs different frequency-doubling crystal of dismounting or frequency multiplication module, brings than burden to use; Particularly in the application of laser radar,, more show its immalleable defective when needs apace during the output wavelength of switched laser.
The summary of the invention the technical problems to be solved in the utility model provides a kind of rational in infrastructure, practical for overcoming weak point of the prior art, uses Nd:YAG laser freuqency doubling switch more easily.
The technical scheme that is adopted comprises the frequency-doubling crystal on Nd:YAG laser and its output optical axis, particularly said frequency-doubling crystal is two frequency-doubling crystals, the output of said two frequency-doubling crystals is equipped with electronic control translation stage, said electronic control translation stage is connected with stepping motor, and be fixed with frequency tripling crystal and quadruple frequency crystal on it, said frequency tripling crystal and quadruple frequency crystal are under the drive of electronic control translation stage, its motion track passes through the output optical axis of two frequency-doubling crystals, and said stepping motor is electrically connected with controllor for step-by-step motor.
As the further improvement of technical scheme, the motion track of described electronic control translation stage is perpendicular to the output optical axis of two frequency-doubling crystals; Described controllor for step-by-step motor is electrically connected with it through the RS of microcomputer 232 ports.
Beneficial effect with respect to prior art is, one, be arranged on the electronic control translation stage of two frequency-doubling crystal outputs, by moving apace, the output optical axis that can make frequency tripling crystal on it and quadruple frequency crystal can momentarily switch to or shift out laser as required, thereby realized the switching of different laser frequency doubling crystals quickly and easily, obtained the output of required different wave length laser; Its two, perpendicular to the motion track of the electronic control translation stage of two frequency-doubling crystal output optical axis, make frequency tripling crystal and quadruple frequency crystal be able to or withdraw from the output optical axis of two frequency-doubling crystals perpendicular to the output optical axis incision; Its three, controllor for step-by-step motor is connected with microcomputer, and the controllability of electronic control translation stage and whole automaticity all are improved.
Description of drawings is described in further detail optimal way of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a kind of basic structure schematic diagram of the present utility model.
Embodiment is referring to Fig. 1, and it is the laser of 1064nm that Nd:YAG laser 1 is selected output wavelength for use, is equipped with two frequency-doubling crystals 2 on its output optical axis.The output of two frequency-doubling crystals 2 is provided with the electronic control translation stage 5 of its motion track perpendicular to two frequency-doubling crystals, 2 output optical axis, fixing the frequency tripling crystal 3 and the quadruple frequency crystal 4 that have accurate adjustment rack on this electronic control translation stage 5, the bottom of electronic control translation stage 5 is connected with stepping motor 6.Stepping motor 6 is electrically connected with the output of controllor for step-by-step motor 7, and the input of controllor for step-by-step motor 7 is electrically connected with RS 232 ports of microcomputer 8.Two above frequency-doubling crystals 2 or frequency tripling crystal 3 or quadruple frequency crystal 4 all can be selected corresponding two frequency multiplication modules or frequency tripling module or quadruple module for use.
Before the use, respectively frequency tripling crystal 3 and quadruple frequency crystal 4 are on the laser beam optical axis of two frequency-doubling crystals, 2 outputs earlier, regulate the orientation of frequency tripling crystal 3 and quadruple frequency crystal 4 subtly by adjustment rack, with the phase matched of the laser of realizing itself and 2 outputs of two frequency-doubling crystals.During use,, control the shift position of electronic control translation stage 5, make frequency tripling crystal 3 and quadruple frequency crystal 4 lay respectively at the relevant position by microcomputer 8 according to needed optical maser wavelength.As needs 355nm wavelength laser, then mobile electronic control translation stage 5 is on the optical axis of two frequency-doubling crystals, 2 outputs the frequency tripling crystal 3; As needs 266nm wavelength laser, then mobile electronic control translation stage 5 is on the optical axis of two frequency-doubling crystals, 2 outputs quadruple frequency crystal 4; As needs 532nm wavelength laser, then mobile electronic control translation stage 5 all is not on the optical axis of two frequency-doubling crystals, 2 outputs frequency tripling crystal 3 and quadruple frequency crystal 4.
Obviously, those skilled in the art can carry out various changes and modification to Nd:YAG laser freuqency doubling switch of the present utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
