The World of Pulse Pickers: Enhancing Laser Systems

Introduction

Pulse pickers play a crucial role in enhancing the performance of ultrafast laser systems by selectively extracting individual pulses from a pulse train. This technology is essential in various applications such as femtosecond and picosecond laser systems.

UHG Pulse Selector

The UHG Pulse Selector, offered by GWU, is designed for ultrafast laser oscillators. It provides high output powers and optimal contrast ratio for pulse picking. The system can handle high input powers for femtosecond and picosecond pulses without needing attenuation. It allows for integral pulse selection from single shot to 40 MHz with adjustable contrast ratio through user-friendly software control. The selector can be used as a standalone version or integrated into a Harmonic Generator for a compact solution.

PulseSelect by APE

PulseSelect by APE offers pulse pickers for specific wavelength ranges, catering to different laser systems. It utilizes acousto-optical elements to achieve high repetition rates and contrast ratios. The system allows for pulse repetition rate adjustment through internal frequency division or external triggering, minimizing pulse distortion.

ALPHALAS Pulse Pickers

ALPHALAS provides advanced pulse pickers capable of selecting single pulses from picosecond or femtosecond optical trains. With features like large amplitudes, short pulse widths, and high repetition rates, these pulse pickers ensure precise synchronization and pulse selection from mode-locked lasers.

Pulse Picker Synchronization Tool

The Pulse Picker synchronization tool by SHIPS TODAY is designed to drive external modulation devices in a pulse-picking mode. It offers various pulse picking modes and includes features like adjustable input voltage thresholds and burst shaping for mode-locked lasers.

ModBox-OPP Optical Pulse Picker

The ModBox-OPP optical pulse picker acts as a fast gate for picking and shaping sub-nanosecond pulse patterns in an incoming pulse train. It provides high stability, low insertion loss, and user-adjustable optical pulse parameters for precise pulse selection.

EKSMA Optics Laser Pulse Picking System

The opto-electronic laser pulse picking system by EKSMA Optics allows for picking femtosecond pulses from pulse trains at high repetition rates. With synchronization capabilities with lasers operating at different rates, this system offers flexibility and precision in pulse selection.

Conclusion

Pulse pickers are essential components in ultrafast laser systems, enabling precise pulse selection and synchronization for various applications. Understanding the capabilities of different pulse picker technologies is crucial in optimizing laser system performance for research, industrial, and medical applications.
