DKDP electro-optic Q-switch is a high-performance Q-switch device made by using the characteristics of high electro-optic coefficient of DKDP. Its modulation effect is stable, the pulse width is small, and the applicable range is wide. It is widely used in many laser fields. It is also the most ideal electrooptic modulation device for pulsed lasers, including: beauty, medical, research and development, military, and aerospace laser fields.
Advantages:
1. High deuterium content (>98.0%) in DKDP crystals
2. No static birefence
3. No damage from optical refraction
4. Good environmental tolerance
5. High damage threshold
6. Compact design
7. Easy to adjust
8. electro-optic coefficient
9. Good sealing without adhesives
