RTP


RTP Crystal's transparent range is from 350nm to 4500nm,with a high dielectric constant(ε=11)and resistivity(approximately 1011-1012Ω·cm),a high laser damage threshold(1.8 times higher than that of KTP crystal),and an extremely low piezoelectric ringing effect.

Classification:


RTP(RbTiOPO4)belongs to KTP family.The transparent range of RTP crystal is from 350nm to 4500nm,with a high dielectric constant(ε=11)and resistivity(approximately 1011-1012Ω·cm),a high laser damage threshold(1.8 times higher than that of KTP crystal),and an extremely low piezoelectric ringing effect.Therefore,it is well suited for electro-optic modulation of lasers,including Q-switches,electro-optic shutters,phase modulators,pulse pickers,cavity dumpers,etc.

RTP is a biaxial crystal.To eliminate the influence of environmental temperature changes on the refractive index,RTP electro-optic devices typically use two crystals of equal length and performance parameters,with their optic axes perpendicular to each other.Such a dual-crystal device can operate stably in an environment ranging from-50℃to+70℃.Moreover,the serial connection of the dual crystals further reduces the modulation voltage of the device,making it more suitable for military laser rangefinders and medical lasers.
