SESAM (Semiconductor Saturable Absorber Mirror ) mode-locked ultrafast pulsed lasers represents an important breakthrough in the development of mode-locked lasers, but a key challenge remains, that is, extending SESAM technology to the mid-infrared (MIR) region.

Wide Temperature Range LiNbO3 Pockels Cell is a Pockels cell based on a lithium niobate (LiNbO3) crystal. It is designed as a Q-switch for polarizers using pulsed solid-state lasers (Nd:YAG/Ce/Nd:YAG and Nd:YAP. This electro-optic switch operates at a working wavelength of 1.05-1.08 μm generated by pulse pumping.

Crystrong’s Large Aperture DKDP Pockels Cells are specially designed for high power, high energy, large spot applications.
It possesses an extinction ratio of >2000:1 (measured using a 632 nm He-Ne laser) with a transmittance of >98%.

Crystrong's DKDP Pockels Cells possess an extinction ratio of >2000:1 (measured using a 632 nm He-Ne laser) with a transmittance of < 98%.
The DKDP electro-optic Q- switching capacitor is small (about 3-5pF), so the rise time is short (<0.5ns).

The 694&755 DKDP Pockels Cells are specially designed for unique purposes in medical aesthetic applications. Particularly suitable for 694nm and 755nm wavelengths. 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%.

RTP is an ideal candidate for a wide variety of Electro-Optic applications as Pockels cells, shutters, Q-switch, phase modulators, attenuators, pulse pickers and more.
The outstanding electro-optical parameters allow extremely fast switching (rise/fall time under 1ns) and high repetition rates (over 1MHz) without ringing. RTP EO cells are assembled in a thermally compensated double-crystal configuration, in which two matched crystals are placed in line of the propagation axis (x or Y) with one rotated by 90 degrees.

BBO-based pockels cell are used to change the polarization state of light passing through it when an voltage is applied to the electrodes of BBO electro-optic crystals. Typical applications include Q- switching of the laser cavity, laser cavity dumping and coupling light into and form regenerations amplifiers. Low piezoelectric ringing makes BBO Pockels cell attractive for the control of high-power and high repetition rate lasers.

Proton exchange method and metal diffusion method are the most common methods to prepare lithium niobate waveguide, due to the use of these two methods of the preparation of waveguide device waveguide differ with the refractive index of substrate layer is small, light limit function is weak, and in the process of making the introduction of foreign ions can destroy the properties of lithium niobate crystal, so as to affect the performance of the waveguide.

Multi-function integrated optical chip (MIOC, or Y Waveguide Modulator) is a key component in Fiber Optic Gyroscope (FOG) for measuring angular velocity of an inertial navigation system.
