    • Mofuta oa I le mofuta II o sa amaneng le boemo ba mohato (NCPM) ka bolelele ba bokahohle;
    • Spectral NCPM haufi le 1300nm.
    Likopo:
    • Lits'ebetso tse fetang 480mW ho 395nm li hlahisoa ke makhetlo a imenneng habeli mochini oa Ti o notletsoeng ka 2W: Sapphire laser (<2ps, 82MHz). Boima ba bolelele ba 700-900nm bo koahetsoe ke kristale ea 5x3x8mm3 LBO.
    • Ho hlahisoa lihlahisoa tse tala tse fetang 80W ke SHG ea Q-switched Nd: YAG laser ka mofuta oa II 18mm bolelele ba LBO.
    • Makhetlo a mabeli a habeli a diode a pompetsoeng Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) e fihlela ts'ebetso e fetang 40% ea ho fetoha ka kristale ea LBO e 9mm.
    Tlhahiso ea VUV ka 187.7 nm e fumanoa ka tlhahiso ea kakaretso ea maqhubu.
    • Lehlaseli la 2mJ / pulse diffraction-limited ho 355nm le fumanoa ka maqhubu a sephiri a hatang Q-switched Nd: YAG laser.
    • Ho fumanoe bokhoni bo phahameng ba phetoho le 540-1030nm tunable wavelength range le OPO e pompetsoeng ho 355nm.
    • Mofuta oa I OPA o pompetsoe ho 355nm ka tšebetso ea phetoho ea matla ea pompo-to-signal ea 30% e tlalehiloe.
    • Mofuta oa II oa NCPM OPO o pompetsoeng ke laser ea XeCl excimer ho 308nm o fihletse katleho ea 16.5% ea phetoho, mme mekhahlelo ea wavelength e itekanetseng e ka fumaneha ka mehloli e fapaneng ea pompo le tokiso ea mocheso.
    • Ka ho sebelisa mokhoa oa NCPM, thaepa I OPA e pompetsoeng ke SHG ea Nd: laser ea YAG ho 532nm le eona e bonoe ho koahela sebaka se seholo sa tokiso ho tloha ho 750nm ho isa ho 1800nm ​​ka mocheso o tsoang ho 106.5 ℃ ho isa ho 148.5 ℃.
    Ka ho sebelisa mofuta oa II NCPM LBO joalo ka jenereithara ea parametric Optical (OPG) ebe u thaepa BBO e ts'oanang le karolo ea BBO joalo ka OPA, moeli o moqotetsane (0.15nm) le phallo e phahameng ea phepelo ea matla (32.7%) ha e pompeloa ke 4.8mJ, 30ps laser ho 354.7nm. Litsela tsa Wavelength ho tloha 482.6nm ho isa 415.9nm li koahetsoe ka ho eketsa mocheso oa LBO kapa ka ho potoloha BBO.
