POCKEL CELL DRIVER
For a transverse field device, the half wave voltage is determined by amongst other things, the ratio of length to aperture higher being more favorable. The apparent benefits of lower switching voltage are however often outweighed pockel cell other factors. To make use of this effect, light must propagate through the crystal normal to a direction in which the refractive index change can be produced.

These components combine in space to form generally elliptical polarization states linear and circular polarization being special forms of elliptical polarization. For uses and applications of Pockels cells like the UPC, look in the Application Notes section then give us a call to discuss your requirements. By using this method, a clean electrical interface is presented to the driving circuit and internal reflections are minimised. Note: this box searches only for keywords in the pockel cell.
If the microscope's main shutter is placed before the Pockels Cell, the cell heats up while the shutter is open and cools down when the microscope is inactive and the shutter is closed. To ensure the Pockels Cell reimains in thermal equilibrium, the shutter should be located after the Pockels Cell. Connect the Pockels Cell to the high voltage driver as described in the user manual. Connect the command input on the driver board to an AO analog output of the ScanImage system. For a Conoptics RM driver, the switches should be set as indicated in pockel cell graphic to the right. Although the cells can be driven up to 20 kHz, they experience piezoelectric ringing at frequencies beyond 5 kHz.
We do not recommend driving at these pockel cell unless this ringing is acceptable in your application. For general use, a power supply capable of up to 5 kHz modulation and 5 - 6 kV output is recommended. For applications such as Q-switching, fast rise times on the order of 50 ns are desired and the user should ensure that his or her power supply is capable providing such fast rise times. To create the electrical connections, these Pockels cells have two electrical sockets for 1 mm pins. Please note that Thorlabs does not currently offer Pockels pockel cell drivers. Thorlabs' Pockels cells should not be disassembled under any circumstances.
For more information, please feel free to contact the United Crystals' technical support team. Other antireflection coatings are available under request. Specifications are subject to changes without advance notice. The Pockels effect occurs only in crystals that lack inversion symmetrysuch as lithium niobateand in other noncentrosymmetric media pockel cell as electric-field poled polymers or glasses.
Pockels cells are voltage-controlled wave plates. The Pockels effect is the basis of the operation of Pockel cell cells.
BBO Pockels Cells
pockel cell ScanImage blanks the beam during scanner turnaround to avoid overexposing the sample. Since the Pockels Cell does not respond to a changed control voltage instantaneously, the image can show blanking artifacts on the left and right edges.
ScanImage can compensate for this effect by shifting the command voltage in time. Typically, a value of 2us is pockel cell. If the power calibration fails, try the following steps.
When they meet in the crystal, their voltages add up. Pockels cells for fibre optics may employ a traveling wave design to reduce current requirements and increase speed. Usable crystals also exhibit the piezoelectric effect to some degree  RTP has the lowest, BBO and lithium niobate are high.

When used in conjunction with polarizer, Pockels cells can be used as fast optical switches. Contact Me:.
