Background technology
In recent years,, be used widely at numerous areas such as optics, communication, medical science, military affairs along with the fast development of laser technology, all solid state laser particularly is little because of its volume, price is low, advantages of simple structure and simple people's attention extremely.All solid state laser generally all is to produce laser by laser diode-pumped laser crystals, can produce the laser of 1064nm as pump-coupling Nd:YAG.The pumping laser crystal generally can only produce infrared laser, and can not obtain short wavelength's laser, and the laser that will produce shorter wavelength just must carry out frequency multiplication, sum of fundamental frequencies, difference frequency etc. with non-linear optic crystal, such as using non-linear optic crystal KTiOPO 4(KTP) the 1064nm laser that Nd:YAG is produced carries out frequency multiplication, can obtain the green laser of 532nm; Use non-linear optic crystal LiB 3O 5(LBO) the 1064nm laser that Nd:YAG is produced carries out the violet laser that frequency multiplication, sum of fundamental frequencies can get 355nm.Short wavelength's laser is because of its single photon energy height, and wavelength is short, in fields such as information storage, precision sizing, precision instrument, biological medicine, military affairs irreplaceable effect is arranged.Except aforesaid method, also can directly obtain short wavelength laser by laser diode pump-coupling self-frequency doubling laser crystal.So-called self-frequency doubling laser crystal mixes rare earth ion exactly in non-linear optic crystal, as Nd:YAB, YAB is YAl 3(BO 3) 4Abbreviation, YAB itself is a kind of nonlinear optical material, when its is planted mix the Nd ion after, just become self-frequency doubling laser crystal.All can mix rare earth ion in not all nonlinear optical material becomes self-frequency doubling laser crystal, just not all right such as above-mentioned KTP and LBO.The non-linear optic crystal that only comprises the element similar with the rare earth ion atomic radius just might become self-frequency doubling laser crystal.Resemble and contain yttrium (Y) element among the YAB, itself belongs to rare earth element, therefore has similar atomic radius and character with other rare earth elements, therefore can be replaced by other rare earth elements, so can become self-frequency doubling laser crystal.
At present, more famous non-linear optical crystal material mainly contains following several: KTiOPO 4(KTP), LiB 3O 5(LBO), β-BaB 2O 4(BBO), CsB 3O 5(CBO), CsLiB 6O 10(CLBO), K 2Al 2B 2O 7(KABO), KBeBO 3F(KBBF) etc.This different materials more or less all has certain shortcoming, such as, although the KTP non-linear effect is bigger, damage threshold is lower, can not produce high power laser; Although LBO, BBO, CBO, CLBO and KABO damage threshold are big but non-linear effect is less, and BBO, CBO, CLBO can not use in high humidity environment; Though it is shorter that the KBBF ultraviolet sees through wavelength, but the laser of 177nm produced, but Be unit have severe toxicity, and human body and environment are made a big impact, and this crystal of growth of large size high quality is relatively more difficult.In addition, some borates of bismuth-containing (Bi) element have caused extensive concern in recent years, not only comprise BO because produce the group of non-linear effect in these compound structures 3Group and comprise the lone-pair electron of Bi-O group, this makes this compounds have bigger non-linear effect, such as BiB 3O 6(BIBO) has d Eff( )=3.2pm/V, than KTP(＜2.7pm/V) big, and BIBO also has bigger damage threshold.
As noted earlier, become self-frequency doubling laser crystal, at first this host crystal must have the non-linearity effect, and next has the similar atom that can be replaced by rare earth ion.At present, the material that can be used as self-frequency doubling laser crystal has YAl 3(BO 3) 4(YAB), YCa 4O(BO 3) 3(YCOB), Na 3La 9O 3(BO 3) 8(NLBO), CaLa 2B 10O 19(LCB).These several crystalline shortcomings mainly are that non-linear effect is less, and this makes that the lasing efficiency that obtains is lower.
