DKDP or  KD*P crystals have high electro-optic coefficients, which makes well-suited for pockels cells Q-switches applications. DKDP crystals also have good transmission at 0.3 to 1.1µm, a high deuteration rate (D>97% – 98% )  contributes to effective electro-optical coefficients. The operation range of  DKDP (KD*P) Pockels cells for Q-switching applications are conventionally 400 nm to about 1.1 μm. Virtually most of low repetition rate DPSS Nd:YAG lasers  and commercial flashlamp pumped Nd:YAG lasers are equipped with DKDP (KD*P) based Pockels cells for laser cavity Q-switching. DKDP Pockels cells are widely used in laser systems with large caliber, high power and narrow pulse width, with excellent physical and optical property.
Hangzhou Shalom EO offers the DKDP pockels cells with high deuteration (>98%), low capacitance and fast rise time and high transmission, high extinction ratio, the largest aperture of 50mm is available. 
Features:

    • Low absorption and high deuteration 
    • Longitudinal modulation, so applied voltage does not depend on crystal aperture, hence large apertures are available
    • High damage threshold dielectric AR coating options
    • For fs applications due to low GVD

    Applications:

    • Pulse picking and Laser cavity dumping
    • Q-switching of  low repetition rate diode pumped lasers and flashlamp pumped high energy lasers
    • OEM laser systems
    • Medical/cosmetic lasers
    • Versatile R&D laser platforms
    • Military & aerospace laser systems

    Common Specifications:

    Deuteration of DKDP Crystals >98% Wavelength Range 300nm to 1400nm
    Aperture ≦50mm Wavefront Distortion Lambda/8@633nm
    Capacitance ~3pF Quarter Wave Voltage ~3200V
    Transmission (@designed wavelength) >98%

    Side physical effcets of Pockels cells:

    When it comes to practical applications of Pockels cells, one may need to take some additional side effects into account:

    • Etalon effects may still exists and affect the optical performance if the beam direction is perpendicular to the faces of crystal, Even when the end faces of the crystal are coated with high-quality AR coatings.
    • Temperature could significantly affect the obtain phase changes.For example, a Pockels cell which is set to generate perfect high-contrast amplitude modulation, may require readjustments of the operation voltages when the temperature changes. However there are thermally compensated double crystal designs may circumvent the problem.
    • For operation with large beam radius, it is worth paying attention to sort out an optimized design for electrodes (possibly with additional auxiliary electrodes for high uniformity of the generated electric field, as otherwise one may obtain a spatially varying modulation).
    • Nonlinear crystals often exhibit substantial piezo-electric and elastooptic effects, which can have substantial influences on the performance at high modulation frequencies.
    • Operating at high power levels, thermal effects may be induced by residual absorption of the crystal . Therefore materials with lower absorption are preferable for high power applications
    • The crystals used in Pockels cells are nonlinear crystal materials, they inherently demonstrates considerable optical nonlinearities. For instance, self-phase modulation and nonlinear self-focusing might occur for light pulses with substantial peak power.
