RTP Crystals

RTP Crystals cater to world of Electro Optics mass marke .
iRTP is the advanced version of RTP. To add on RTP crystals is used in wide range of pockel cells applications, shutters, Q-switch, attenuators, modulators and many more.
The two important parameters which make them special are high repetition rate up to 1MHz and fast switching time (rise and fall time under 1ns).
The best thing about RTP cell is they perform well over wide range of temperature ie.from ‐50◦C to +70◦C.
Pockels cell adjustment – iRTP requires single dimension alignment, which allows a much simpler and faster alignment process, with a better extinction ratio.

Overview

RTP Crystals (Rubidium Titanyl Phosphate) are widely used in the electro-optics industry for a variety of applications, including Pockels cells, shutters, Q-switches, attenuators, and modulators. Their versatility and reliability have made them a popular choice in mass-market electro-optics.

The iRTP is an advanced version of RTP, offering enhanced performance. Two standout features of RTP and iRTP are their high repetition rate, capable of reaching up to 1 MHz, and fast switching times, with rise and fall times of less than 1 nanosecond.

A major advantage of RTP cells is their ability to perform across a wide temperature range, from -50°C to +70°C, making them ideal for use in diverse environments. Additionally, iRTP simplifies the alignment process by requiring only single-dimensional alignment, resulting in faster setup and improved extinction ratios.

Key Features

Simple 1D Alignment: The iRTP Pockels Cell requires only one-dimensional alignment to achieve optimal extinction ratio, simplifying the setup process and reducing alignment time.
Environmental Stability: With its non-hygroscopic material and temperature compensation design, iRTP operates reliably in non-controlled environments, tolerating a wide range of temperatures and humidity levels without performance degradation.
Mechanical Robustness: The single-dimension alignment allows for a more mechanically stable and simpler design. iRTP’s performance remains consistent over time, requiring minimal calibration and ensuring long-term stability, even with temperature fluctuations.
High Repetition Rate: Supports a repetition rate up to 350 kHz, making it ideal for high-speed laser applications.
High Damage Threshold: Capable of handling high-power lasers due to its high damage threshold, ensuring durability in demanding laser systems.
Standard Assembly: iRTP is an off-the-shelf product, conforming to standard electro-optic (EO) cell specifications, making it easy to integrate into various systems.
Simpler Laser Design: iRTP enables simpler laser system designs due to its stable operation and reduced complexity.
Improved Thermal Stability: The improved thermal stability of the Pockels Cell eliminates the need for active thermal management, simplifying the system design.
Fewer Components: The iRTP Pockels Cell does not require an oven or complex 4-axis mount, reducing the number of peripheral components and the complexity of the overall system.
Compact Module Footprint: Due to fewer required peripherals, the iRTP Pockels Cell offers a smaller module footprint, allowing for more compact system designs.
