Abstract
The utility model discloses a core device of a lamp-pump double-bar laser, which comprises a KTP crystal frequency multiplier, a full inverse lens, Cr < 4+ >, a YAGQ switch, a light-focusing cavity and a folding mirror, wherein a shock stage Nd: YAG laser crystal bar, an amplification stage Nd: YAG laser crystal bar, a shock stage Nd: YAG laser crystal bar and an amplification stage Nd are parallelly arranged in the light-focusing cavity, a pumping lamp is parallelly arranged between the two YAG laser crystal bars, the utility model is provided with a pair of folding mirrors which are respectively arranged on the corresponding positions which form 45 DEG with a double-bar optical path, and the distance of the double-bar optical path is from 100 mm to 250 mm. The utility model has the technical scheme that a lamp pump and two bars are adopted, the lamp is arranged between the two Nd: YAG bars, and the lamp and the two Nd: YAG bars are arranged in the same light-focusing cavity. Therefore, the utility model combines the two stages of shock and amplification into a whole body, the volume is reduced and the utility model not only reduces the product cost but also reduces the loss of energy.
Description
Technical field the utility model belongs to the laser technique field, is specifically related to an a kind of lamp pump double stick laser core apparatus.
The laser core apparatus of background technology prior art comprises the ktp crystal frequency multiplication, the lens that are all-trans, Cr
4+: YAG Q switching, laser pump cavity and refrative mirror, alternately be provided with in the said laser pump cavity concussion level Nd:YAG laser crystal bar, amplifying stage Nd:YAG laser crystal bar and respectively with the corresponding pumping lamp of described double stick.Promptly utilize Nd:YAG electric-optically Q-switched, the one-level vibration adds one-level amplifies, and it is burnt to export 1.06 microns about 800 millis of laser, burnt through about 350 millis of 0.53 micron laser of ktp crystal frequency multiplication output.The laser core apparatus of this structure, because double stick linearly is provided with, the laser pump cavity volume is big, the product cost height.
The summary of the invention the purpose of this utility model provides the lamp pump double stick laser core apparatus that a kind of volume is little, product cost is low, to remedy the deficiencies in the prior art.
To achieve these goals, the technical scheme taked of the utility model one lamp pump double stick laser core apparatus is: it comprises the ktp crystal frequency multiplication, the lens that are all-trans, Cr
4+: YAG Q switching, laser pump cavity and refrative mirror, its main points are parallel concussion level Nd:YAG laser crystal bar and amplifying stage Nd:YAG laser crystal bars of being provided with in the laser pump cavity, parallelly between said concussion level Nd:YAG laser crystal bar and the amplifying stage Nd:YAG laser crystal bar double stick are provided with a pumping lamp; Said refrative mirror is an a pair of, be separately positioned on corresponding position, said double stick optical path angle at 45 on, the distance of said double stick optical path is 100～250mm.
Said two 45 degree refrative mirrors are two speculums.
Said two 45 degree refrative mirrors are two right-angle prisms.
The utility model adopts a lamp pump double stick scheme.One lamp is placed between two Nd:YAG rods, and place in the same laser pump cavity.So just, will vibrate with amplifying two-stage and two is one, has dwindled volume greatly, has not only reduced product cost, has also reduced the loss of energy.
Appended drawings 1 is the utility model structural principle schematic diagram.
Embodiment with reference to the accompanying drawings, the utility model one lamp pump double stick laser core apparatus, it comprises ktp crystal frequency multiplication 1, lens 5, Cr are all-trans
4+: YAG Q switching 6, laser pump cavity 2 and refrative mirror 9, parallel concussion level Nd:YAG laser crystal bar 8 and the amplifying stage Nd:YAG laser crystal bar 3 of being provided with in the laser pump cavity 2, the parallel pumping lamp 7 that is provided with between concussion level Nd:YAG laser crystal bar 8 and amplifying stage Nd:YAG laser crystal bar 3 double sticks; Said refrative mirror 9 is an a pair of, be separately positioned on corresponding position, said double stick 8,3 light paths, 4 angles at 45 on, the distance of said double stick 8,3 light paths 4 is 100～250mm.
Two 45 ° of refrative mirrors 9 are two speculums or are two right-angle prisms.
The utility model one lamp pump double stick laser core apparatus, optical path distance must be greater than 100 millimeters between oscillator stage and the amplifying stage.In order to realize a lamp pump double stick, two 45 ° of speculums or right-angle prism folding scheme have been adopted.When optical path distance was too small between oscillator stage and the amplifying stage, amplifying stage added radiation of oscillator stage superfluorescence and amplification to the feedback of oscillator stage, makes Cr
4+: YAG is bleaching ahead of time, pump energy can not be added, otherwise just multiple-pulse occurs.Distance is far away more between oscillator stage and the amplifying stage, and amplifying stage is more little to the feedback of oscillator stage.Thereby selected distance is between 100～250mm.But spacing is excessive, and machine volume is strengthened, and inconvenience is adopted.
Claims (3)
