KTP Crystal
Potassium Titanyl Phosphate (KTiOPO4 kapa KTP) KTP ke lisebelisoa tse sebelisoang haholo bakeng sa ho habeli habeli ha Nd:YAG le li-lasers tse ling tsa Nd-doped, haholo ha matla a matla a le maemong a tlase kapa a mahareng.Ho fihlela joale, maqhubu a eketsehileng le a intra-cavity a imenneng habeli Nd: lasers e sebelisang KTP e fetohile mohloli o ratoang oa ho pompa bakeng sa li-laseser tse bonahalang tsa dae le li-laser tsa Ti: Sapphire lasers hammoho le li-amplifiers tsa tsona.Hape ke mehloli e metle e tala bakeng sa likopo tse ngata tsa lipatlisiso le indasteri.
KTP e boetse e sebelisoa bakeng sa ho kopanya intracavity diode ea 0.81µm le 1.064µm Nd:YAG laser ho hlahisa leseli le leputsoa le intracavity SHG ea Nd:YAG kapa Nd:YAP lasers ho 1.3µm ho hlahisa leseli le khubelu.
Ntle le likarolo tse ikhethang tsa NLO, KTP e boetse e na le EO e tšepisang le thepa ea dielectric e ka bapisoang le LiNbO3.Lisebelisoa tsena tse ntle li etsa hore KTP e be molemo haholo ho lisebelisoa tse fapaneng tsa EO.
KTP e lebelletsoe ho nka sebaka sa kristale ea LiNbO3 ts'ebelisong e kholo ea molumo oa li-modulator tsa EO, ha melemo e meng ea KTP e kopanngoa, joalo ka tšenyo e phahameng, bandwidth ea optical (> 15GHZ), botsitso ba mocheso le mochini, le tahlehelo e tlase, jj. .
Likarolo tse ka sehloohong tsa Likristale tsa KTP:
● 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)
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
