KTP - Maqhubu a Mangata a Nd: Lasers ea Yag Le Li-Laser tse ling tsa Nd-doped
Tlhaloso ea Sehlahisoa
KTP ke lisebelisoa tse sebelisoang haholo bakeng sa ho phetoa khafetsa ha li-lasers tsa Nd:YAG le li-lasers tse ling tsa Nd-doped, haholo-holo ka matla a tlase kapa a mahareng.
Melemo
● Phetoho e sebetsang hantle (1064nm SHG e sebetsa hantle ka 80%).
● Li-coefficients tse kholo tsa mahlo tse sa tsitsang (makhetlo a 15 ho feta KDP)
● Wide angular bandwidth le sebaka se senyenyane sa ho tsamaea
● Mocheso o pharaletseng le bandwidth ea spectral
● Thermal conductivity e phahameng (makhetlo a 2 ho feta a kristale ea BNN)

● Bokaholimo bo bentšitsoeng haholo
● Ha ho na ho bola ka tlase ho 900°C
● E tsitsitse ka mochine
● Theko e tlaase ha e bapisoa le BBO le LBO
Lisebelisoa
● Frequency Doubling (SHG) ea Nd-doped Lasers for Green/Red Output
● Frequency Mixing (SFM) ea Nd Laser le Diode Laser bakeng sa Blue Output
● Mehloli ea Parametric (OPG, OPA le OPO) bakeng sa 0.6mm-4.5mm Tunable Output

Phetoho ea Khafetsa
KTP e ile ea hlahisoa ka lekhetlo la pele e le kristale ea NLO bakeng sa lisebelisoa tsa laser tsa Nd tse nang le katleho e phahameng ea phetoho. Tlas'a maemo a itseng, katleho ea phetoho e tlalehiloe ho 80%, e sieang likristale tse ling tsa NLO morao haholo.
Haufinyane tjena, ka nts'etsopele ea li-laser diode, KTP e sebelisoa haholo joalo ka lisebelisoa tsa SHG ka har'a diode pumped Nd: YVO4 solid laser systems ho ntša laser e tala, hape le ho etsa hore laser system e kopane haholo.
KTP Bakeng sa OPA, Likopo tsa OPO
Ntle le ts'ebeliso ea eona e pharaletseng joalo ka sesebelisoa se habeli habeli ho sistimi ea laser ea Nd-doped bakeng sa tlhahiso ea Green/Red, KTP hape ke e 'ngoe ea likristale tsa bohlokoa ka ho fetisisa mehloling ea parametric bakeng sa tlhahiso e ka sebelisoang ho tloha ho tse bonahalang (600nm) ho isa bohareng ba IR (4500nm) ka lebaka la ho tsebahala ha mehloli ea eona e pompetsoeng, motsoako oa mantlha le oa bobeli oa lasers ea Nd:YAG kapa Nd:YLF.
E 'ngoe ea lisebelisoa tse molemo ka ho fetisisa ke "non-critical phase-matched" (NCPM) KTP OPO/OPA e pompetsoeng ke li-laseser tse tunable ho fumana katleho e phahameng ea phetoho. le maemo a karolelano ea matla a milli-watt ho mats'oao le liphetho tse sa sebetseng.
E pompetsoe ke li-lasers tsa Nd-doped, KTP OPO e fumane ka holimo ho 66% e sebetsang hantle bakeng sa phetoho e tlase ho tloha 1060nm ho ea ho 2120nm.
Electro-Optical Modulators
