Phase retardation plates, or waveplates, are polarizing optics used to manipulate the polarization state of the transmitting light without attenuating, deviating, or displacing the light. The working principle of the plate is to utilize the birefringence of certain materials which separates the incident light beam into two beams along two orthogonal optical axes within the medium. The phase retardation between the two beams of the incident light contributes to changes in the polarization state.

Polarizer is a kind of optical filter where the light transmission depends strongly on the polarization state. Normally, light with linear polarization in a certain direction is passed, and light polarized in an orthogonal direction is either absorbed or propagated to a different direction.For other directions of linear polarization with an angle θ against the“passing”direction, the transmission exhibits a cos2 θ dependence. That can be understood by considering that linear polarization state as a linear superposition of the "passing”and the“blocked”state.Most polarizers act

BBO features good optical transparency from around 200nm to over 2µm, offers a high resistance to optical damage with power handling >3GW/cm2 for 1ns pulses at 1064nm. It is possible to use BBO Pockels cells at average power levels of hundreds of watts and power densities of several kW/cm2. In addition, BBO Q-switches have very low levels of piezo-electric resonances.

Polarization optics is important for both intra and extra cavity use. By using high contrast thin film polarizers in their design, laser engineers can save weight and volume within the laser system without influencing the output. Compared with polarizing prisms, polarizers have larger incident angle and can be made with larger apertures. Compared with polarizers made from birefringent crystals, the advantage of thin film polarizers made from UVFS or N-BK7 is that they can be fabricated in very large sizes, therefore are particularly well suited for high laser powers and UV wavelengths.

LiNbO3 crystal is a low cost photoelectric material with good mechanical and physical properties as well as high optical homogeneity. It has been widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064nm as well as quasi-phase-matched (QPM) devices. With preferable E-O coefficients, LiNbO3 crystal has become the most commonly used material for Q-switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc.

RTP possesses a large electro-optic impact for light propagating along either the x or y direction (electric powered along z). It functions right optical transparency from around 400nm to over 4µm. RTP offers a high resistance to optical damage with energy ~1Gw/cm2 for 1ns pulses at 1064nm. It is largely total lack of piezo-electric resonances at 200kHz and probable beyond. The primary distinction between RTP and BBO whilst used for Q-switching pertains to the common power degree at which the Q-switch is capable of be used practically.

Yb:YAG's advantage is a wide pump band and an excellent emission cross section. It is ideal for diode pumping. The broad absorption band enables Yb:YAG to maintain uninterrupted pump efficiency across the typical thermal shift of diode output. High efficiency means a relatively small dimension Yb:YAG laser crystal will produce high power output. Based on the YAG host crystal, Yb:YAG can be quickly integrated into the laser design process.

Nd:YVO4 (Neodymium-doped Yttrium Vanadate) is one of the best commercially available material for diode-pumped solid-state lasers, especially for lasers with low or middle power density.

A Pockels cell driver is a high-voltage regulated power supply, either pulse or continuous, allowing to control a birefringence of an electro-optical crystal (KTP, KD*P, BBO, etc.) in order to drive the polarization direction of the light propagating through the crystal.WISOPTIC has developed and produces a variety of Pockels cell drivers for different applications: from very simple compact devices for q-switching to precise and powerful fast models for pulse picking, cavity damping, regenerative amplifier control, etc.
