KTA Crystal
KTA (Potasium Titanyle Arsenate, KTiOAsO)4 ) ke kristale ea mahlo a sa shebaheng e tšoanang le KTP eo atom P e nkeloang sebaka ke As. E na le thepa e ntle eo e seng ea methapo ea methapo ea mahlo le ea motlakase, mohlala, ho fokotsoa haholo ho amoheloa ha sehlopha sa 2.0-5.0 µm, bandwidth e pharaletseng le mocheso.
Ha ho bapisoa le KTP, melemo ea mantlha ea KTA e kenyelletsa: Coefferior e phahameng ea odara ea bobeli ea bobeli, matla a malelele a IR a khaotsoeng, le ho kenngoa hanyane ho 3.5 µm. KTA e boetse e na le tsamaiso e tlase ea ionic ho feta ea KTP, e hlahisang ts ebetso e phahameng ea laser e kenyellelitseng ts'ebetso.
KTA e ratoa haholo ke ts'ebeliso ea Optical Parametric Oscillation (OPO) e fanang ka ts'ebeliso e phahameng ea matla a ho fetolela (ka holimo ho 50%) ea radiation ea laser e ka sebetsoang ka lasers e tiileng.
Ikopanye le rona bakeng sa tharollo e nepahetseng bakeng sa ts'ebeliso ea hau ea likhalase tsa Kta.
Melemo ea WISOPTIC - KTA
• Homogeneity e phahameng, boleng bo botle ba ka hare
• Boleng bo holimo ba polishing ea mobu
• Sethunya se seholo sa boholo bo fapaneng (mohlala 10x10x30mm3, 5x5x35mm3)
• Tlhokahalo e kholo ea nonlinear, katleho e phahameng ea phetoho
• Botebo bo pharaletseng ba khanya, bophara bo boholo bo lekanang le mocheso
• Liaparo tsa AR bakeng sa wave wave ho tloha lebone le bonang ho isa ho 3300 nm
• Theko ea tlholisano haholo, ho tlisa kapele
