Detailed Product Description

Regular flux grown KTP has an electric resistivity as low as 10⁶ W×cm, which may exhibit the detrimental electrochromism when subjected to a dc electric field. Electro-optic KTP (EO-KTP) crystals with high electrical resistivity (~10¹¹-10¹²W·cm) have been grown successfully using our own proprietary technology. The electrochromism is not observed under a continuous 500V/mm Z-directed electric field over more than 1000 hours. The well-known isomorphs RTP performance given applies also to EO-KTP which has high damage threshold, large effective electro-optic coefficients and lower half-wave voltage. The Q-switch is built utilizing thermally compensated double-crystal designsAdvantages:

• High Damage Threshold
• No Piezoelectric Ringing
• Low Insertion Loss
• Thermal Compensating Design
• Non-hygroscopic
• High Extinction and Contrast Ratio
