Did You Know?

Laser pulse pickers are acousto-optic modulator (AOM) based devices designed to select pulses of ultrafast laser systems. Ultra-short pulses are in most cases generated by a mode-locked laser in the form of a pulse train, with a repetition rate of 10 MHz to 10 GHz. For various reasons, it is often necessary to pick certain pulses and block others. This can be achieved by using a laser pulse picker. The properties of a pulse picker can be critical based on the application, such as the switching time, maximum repetition rate, energy loss of transmitted pulses, and optical bandwidth, just to name a few.

In simple terms, a Laser Pulse Picker is an electronically controlled optical switch. They are acousto-optic or electro-optic modulator devices used to select specified pulses of laser systems while blocking all the others.

Laser Pulse Pickers: Precision Timing for High-Speed Optical Systems

Laser pulse pickers are essential tools in advanced photonics, enabling precise selection of individual pulses from high-repetition-rate laser sources. By utilizing acousto-optic modulators (AOMs), these devices offer rapid, electronic control over pulse timing, making them indispensable in applications ranging from ultrafast spectroscopy to quantum optics.

What Is a Laser Pulse Picker?

A laser pulse picker is an acousto-optic device that selectively transmits individual pulses from a continuous pulse train. It operates by applying an RF signal to an AOM, creating a dynamic diffraction grating that interacts with the incoming laser beam. By tuning the RF frequency, the device can diffract specific pulses while blocking others, effectively reducing the laser repetition rate.

Key features include:

  • High-speed operation: Capable of selecting pulses at rates up to several gigahertz.

  • Low insertion loss: Ensures minimal attenuation of transmitted pulses.

  • High extinction ratio: Provides excellent suppression of unwanted pulses.

Applications of Laser Pulse Pickers

Laser pulse pickers are utilized across various fields:

  • Ultrafast spectroscopy: Enables time-resolved measurements by isolating individual pulses for detection.

  • Quantum optics: Facilitates experiments requiring precise control over photon timing and synchronization.

  • Laser material processing: Allows for selective pulse delivery in micromachining and engraving applications.

  • Biomedical imaging: Enhances techniques like multiphoton microscopy by controlling pulse timing and intensity.

Choosing the Right Laser Pulse Picker

Selecting an appropriate laser pulse picker involves considering several factors:

  • Wavelength compatibility: Ensure the device is compatible with the laser's operating wavelength.

  • Repetition rate: Match the pulse picker’s capabilities with the laser's repetition rate.

  • Beam diameter: Verify that the device can accommodate the laser beam's size.

  • Control interface: Determine the ease of integration with existing systems, including software and hardware interfaces.
