2. STC Series LiNbO3 Pockels Cells

Our optical grade LiNbO3 crystal has good electro-optic performance, large nonlinear coefficient, good optical uniformity, stable mechanical and chemical properties, no deliquescent, low half-wave voltage, and can be applied to high repetition rate operation. It is high in extinction ratio and laser damage threshold. LN electro-optic Q-switches are widely used in Er:YAG, Ho:YAG, Tm:YAG lasers, and are suitable for low-power Q-switched output, especially in laser ranging. We offer the most compact Q-switches for our customers. Furthermore, we also can custom-design and make the Q-switches according to your specific requirements to meet your various applications.

• Large nonlinear optical coefficient
• Large receiving angle
• Small walk-off angle
• Wide temperature and spectral bandwidth
• High photoelectric coefficient and low dielectric constant
• Non-absorbent, stable chemical and mechanical properties

3. STC Series DKDP Pockels Cells

DKDP electro-optic Q-switches (Q-switch, Pockels Cells) are widely used in high-power, narrow-pulse (<10ns) laser systems due to their unique physical properties and excellent optical quality.

The DKDP crystal is a uniaxial crystal with excellent optical quality with an extinction ratio of ＞2000:1 (measured using a 632 nm He-Ne laser) with a wave front distortion of 98%. The DKDP electro-optic Q-switching capacitance is small (about 3-5pF), so that the rise time is short (<0.5ns), and a narrow pulse width laser beam can be achieved during Q-switching. Compared with the widely used electro-optic crystals on the market, DKDP crystals have higher damage thresholds (＞1GW/cm2) under optical conditions of 10ns pulse width, 1064 nm wavelength and repetition rate 10Hz.

• Wave front distortion: low capacitance
• Short rise time: ~3pf
• High transmittance: ＞98%
• High damage threshold: ＞1GW/cm²
• No static birefringence, no photorefractive damage
• Anti-reflective coated quartz window
• Resistant to ambient temperature shock and excellent electro-optic performance
