KTP Crystal
Potassium Titanyl Phosphate (KTiOPO4 vel KTP) KTP est frequentissima materia frequentiae duplicationis ex Nd:YAG et aliis laserarum Nd-doped, praesertim cum potentia densitatis in gradu parvo vel medio consistit.Ad diem, extra et intra-cavum frequentiam duplicatam Nd: lasers utentes KTP praelati flare principium facti sunt pro visibilibus lasers tingendis et tunable Ti:Sapphirus lasers ac eorum amplificatores.Utiles etiam sunt fontes viridis ad multas investigationes et applicationes industriae.
KTP adhibetur ad intracavitatis permixtionem de 0.81µm diode et 1.064µm Nd:YAG laser ad generandam lucem caeruleam et intracavitatem SHG de Nd:YAG vel Nd:YAP lasers ad 1.3µm ad lucem rubram producendam.
Praeter notas unicas NLO, KTP etiam proprietates dielectricas EO et LiNbO3 comparandas pollicitus est.Hae proprietates proficientes faciunt KTP variis EO artibus apprime utiles.
KTP expectatur cristallum reponere LiNbO3 in magna applicatione modulatorum EO volumine, cum alia merita KTP ratione componuntur, ut limen altum, lata band optica (>15GHZ), thermarum et mechanicarum stabilitas, ac humilis iactura, etc. .
