Description
Vynález se týká absorbérů pro lasery, generující v oblasti 1,3 /im,BACKGROUND OF THE INVENTION The present invention relates to absorbers for lasers generating in the region of 1.3 µm,
V současné době je věnována velká pozornost laserům generujícím na vlnové délce v oblasti 1,3 /im. Jsou to například jódový laser, generující na vlnové délce 1,315 /im, jedna z možných vlnových délek neodymového yttriumhlinitého perovskitového laseru je 1,34/im. Tím současně vzniká potřeba saturovatelných absorbérů pro tuto vlnovou oblast.At present, great attention is paid to lasers generating at wavelengths in the region of 1.3 µm. They are, for example, an iodine laser generating at a wavelength of 1.355 µm, one of the possible wavelengths of a neodymium yttrium-aluminum perovskite laser is 1.34 µm. At the same time, there is a need for saturable absorbers for this wavelength.
V současné době je poměrně velmi málo vhodných barviv a navíc jsou obtížně dostupná.At present there are relatively few suitable dyes and moreover they are difficult to access.
Tento nedostatek odstraňuje saturovatelný absorbér pro lasery, generující v oblasti vlnové délky l,3zum podle vynálezu jehož podstata spočívá v tom, že je vytvořen roztokem (bis(4-dietylaminodithiobenzil)niklu v nitrobenzenu.This drawback is eliminated saturable absorber for laser beam, generating in the wavelength l 3 microns from the invention whose principle consists in that a solution is formed (bis- (4-dietylaminodithiobenzil) nickel in nitrobenzene.
PřikladlHe did
Byl připraven roztok (bis(4-dietylaminodithiobenzil)niklu v nitrobenzenu s extinčním koeficientem 0,42 cm na vlnové délce 1,34,um. Roztok byl vpraven do skleněné kyvety o tloušťce 5 mm. Kyveta byla vložena do optického rezonátoru laseru, který byl tvořen rovinným zrcadlem s odrazivosti větší než 99 % na vlnové délce 1,34 ,um a menší než 1 % na vlnové délce 1,07 ^um, dále polopropustným zrcadlem s odrazivosti 31 % na vlnové délce 1,34 >um a 7 % na vlnové délce 1,07 /im a laserovou tyčí s neodymem dopovaného monokrystalu yttritohlinitého perovskitu o průměru 7 mm a délce 114 mm s čely zkosenými pod úhel 2° a opatřenými antireflexními vrstvami pro vlnové délky 1,07 /im a 1,34/im. Na výstupu laseru byl naměřen gigantický puls na vlnové délce l,34zum o energii 30 mJ a délce 20 ns.A solution of (bis (4-diethylaminodithiobenzil) nickel in nitrobenzene with an extinction coefficient of 0.42 cm at a wavelength of 1.34 µm was prepared. The solution was introduced into a 5 mm thick glass cuvette. consisting of a planar mirror having a reflectivity of more than 99% at a wavelength of 1,34 µm and less than 1% at a wavelength of 1,07 µm; a wavelength of 1.07 µm and a laser rod with a neodymium-doped yttrium-aluminum perovskite single crystal of 7 mm diameter and 114 mm length with fronts bevelled at an angle of 2 ° and provided with antireflective layers for wavelengths of 1.07 µm and 1.34 µm. At the laser output, a gigantic pulse was measured at a wavelength of 1.34 z, with an energy of 30 mJ and a length of 20 ns.
Příklad 2Example 2
Byl připraven roztok (bis(4-dietylaminodithiobenzil)niklu v nitrobenzenu s extinčním koeficientem 0,35 cm na vlnové délce 1,34/um, který byl vpraven do skleněné kyvety o tloušťce 5 mm, a ta vložena do optického rezonátoru laseru, který byl proveden stejně jako v příkladu 1 s tím rozdílem, že laserová tyč měla průměr 5 mm a délku 60 mm, jejíž přední čelo bylo kolmé na osu výbrusu a zadní zkosené o 5°. Na výstupu laseru byl naměřen gigantický puls na vlnové délce 1,34 /um o energii 10 mJ.A solution of (bis (4-diethylaminodithiobenzil) nickel in nitrobenzene with an extinction coefficient of 0.35 cm at a wavelength of 1.34 µm was prepared and placed in a 5 mm thick glass cuvette and inserted into a laser optical resonator which was as in Example 1, except that the laser rod had a diameter of 5 mm and a length of 60 mm, the front face of which was perpendicular to the axis of the cut and the rear bevel 5 °. / µm with an energy of 10 mJ.
