EKSMA Optics, a leading provider of electro-optical components, is highlighted on GoPhotonics for its portfolio of high-performance electro-optic devices. The company has significantly expanded its photonics offerings with a new range of precision-engineered optical and electro-optic components that integrate advanced materials, high-speed electronics, and robust optical designs. The lineup includes Pellin-Broca prisms, ultrafast pulse pickers, high-current laser diode drivers, wavelength-specific Pockels cells, and high-voltage drivers - each optimized for high-performance laser systems and research environments.

This latest expansion reflects the company’s focus on delivering tightly integrated solutions that combine optical precision with fast electronic control, enabling superior performance in demanding applications such as ultrafast spectroscopy, laser micromachining, and nonlinear optics.

Precision Pellin-Broca Prisms for Stable Beam Steering and Dispersion

The 325-1206 prism is a Pellin-Broca type designed for wavelength-selective beam deviation and dispersion control. Built from UV-grade fused silica (UVFS), it features a compact form factor with tight dimensional tolerances of ±0.2 mm.

Engineered for a design wavelength of 546.1 nm, the prism incorporates precise apex angles (79.5° and 60°) to enable accurate spectral separation and beam redirection. Its high surface flatness of λ/10 at 633 nm and 20-10 scratch-dig surface quality ensure minimal wavefront distortion and low scattering losses.

With a clear aperture covering 80% of its physical dimensions, the prism supports efficient beam transmission, making it ideal for spectroscopy, laser tuning systems, and interferometric setups where optical fidelity is critical.

Ultrafast Pulse Pickers for MHz-Rate Pulse Selection

The UP2-BBO-2.5 pulse picker is designed for ultrafast laser systems requiring precise pulse selection at high repetition rates. It supports operation at up to 2 MHz while selecting pulses from laser sources with repetition rates as high as 100 MHz.

Utilizing a BBO-based Pockels cell, the system offers high transmission (>98%) and strong contrast ratios (up to 1:1000 for BBO configurations), ensuring clean pulse isolation.

The integrated driver delivers high-voltage pulses with rise and fall times below 7 ns, enabling rapid switching and precise timing control. Additionally, the system operates across a broad wavelength range from 500 nm to 2000 nm, making it adaptable to a wide range of ultrafast laser platforms.

Combined with the pMaster 4.2 timing generator, the pulse picker provides synchronization accuracy down to tens of picoseconds, supporting applications such as time-resolved spectroscopy, nonlinear optics, and high-precision micromachining.

High-Current Laser Diode Drivers for Stable CW and QCW Operation

The uniLDD-CW-30-80 laser diode driver delivers highly stable current control for both continuous-wave (CW) and quasi-continuous-wave (QCW) operation. It supports input voltages from 12 V to 90 V and provides diode compliance voltages up to 27 V in CW mode.

With maximum output currents ranging from 50 A to 100 A in CW mode - and up to 360 A in pulsed operation - the driver is well-suited for high-power diode applications.

The system maintains exceptional stability with current ripple as low as 0.1% and drift below 0.2% over extended operation periods, ensuring consistent optical output.

Additional features such as programmable control bandwidth (>10 kHz), integrated protection mechanisms (over-temperature, over-current, and interlock shutdown), and optional TEC control make the driver ideal for precision applications in spectroscopy, sensing, and medical laser systems.

High-Speed Pockels Cells for Efficient Electro-Optic Modulation

The PCK6-1560/PCR6-1560 Potassium Titanyl Phosphate (KTP)/Rubidium Titanyle Phosphate (RTP) Pockels Cell is optimized for operation at 1560 nm, a key wavelength in fiber laser systems and telecommunications. These electro-optic devices enable rapid modulation of laser beam polarization with high transmission efficiency and low insertion loss.

Designed for high-speed switching, they support applications such as Q-switching, regenerative amplification, and cavity dumping. Their robust construction ensures high damage thresholds, making them suitable for high-power and ultrafast laser environments.

The precise electro-optic response of these cells allows accurate control over pulse timing and intensity, which is essential for advanced photonics experiments and industrial laser processing.

High-Voltage Pockels Cell Drivers for Fast, Reliable Switching

The DP-250-3.6 Pockels cell driver is part of EKSMA Optics’ DP series, offering high-voltage pulse amplitudes up to 3.6 kV and repetition rates up to 250 kHz, with scalability across the series up to 2 MHz.

It features fast switching performance with rise and fall times below 7 ns and adjustable pulse durations ranging from 100 ns to 5000 ns, enabling precise electro-optic control.

The driver is available in both open-frame and enclosed configurations, providing flexibility for OEM integration or standalone laboratory use. Built-in safety features, efficient thermal management (including water cooling), and stable output polarity ensure reliable operation even in high-demand environments.

These drivers are critical for synchronizing Pockels cells in high-energy laser systems, LiDAR technologies, and ultrafast pulse control setups.

Driving Precision and Performance in Modern Photonics

By combining high-quality optical components with advanced electro-optic and electronic control systems, EKSMA Optics delivers a cohesive ecosystem of solutions for next-generation photonics applications.

From wavelength-selective beam manipulation and MHz-rate pulse picking to high-current laser driving and nanosecond-scale electro-optic switching, this expanded portfolio enables researchers and engineers to achieve greater control, stability, and efficiency in their optical systems.

This strategic expansion reinforces EKSMA Optics’ role as a key enabler of innovation in laser technology, supporting a wide spectrum of applications across scientific research, industrial processing, and advanced optical engineering.
