Where to Buy Pulse Pickers

pulseSelect is an acousto-optic pulse picker, developed for the special demands of femtosecond laser technology. Pulse distortion is minimized by a low dispersive design and the use of reflective optics. High repetition rates and high contrast rates are achieved by using acousto-optical elements. The pulse repetition rate can be reduced by an adjustable internal frequency divider or by external triggering.

APE offers pulse pickers for either a wavelength range from 500 nm to 1600 nm or dual wavelength bands from 340 nm to 540 nm and from 680 nm to 1080 nm.

Based on proprietary technology, ALPHALAS offers most advanced pulse pickers for selecting single pulses from a train of picosecond or femtosecond optical trains. Large amplitudes of > 10 kV, pulse widths FWHM of 7 … 10 ns and repetition rates up to 10 kHz in combination with a specially designed short-crystal Pockels cell are best suited for selecting individual pulses from various mode-locked lasers. Low jitter of < 40 ps and short delay of typically 30 ns guarantee a precise synchronization for perfect pulse selection.

GWU’s UHG-PSK Series has been designed for ultrafast laser oscillators. It offers pulse picking with highest output powers and optimum contrast ratio. The system is suitable for femtosecond and picosecond pulses with high input powers, without requiring any attenuation. Integral pulse selecting from single shot to 40 MHz with adjustable contrast ratio is possible by a convenient software control. The UHG Pulse Selector is either available as standalone version or it can be integrated in our Harmonic Generator, where it is positioned before all harmonic stages to offer all features in a single compact housing.

UHG Pulse Selector features and benefits:

• modular design: standalone version or integrated in our Harmonic Generator
• high pulse picking efficiency
• adjustable contrast ratio
• suitable for high fs/ps power without any attenuation
• convenient and user-friendly software control

With the EKSMA Optics opto-electronic laser pulse picking system, femtosecond pulses can be picked from a pulse train at up to 2 MHz rate. The pulse picker UP2 and digital synchronization and delay pulse generator pMaster 4.2 can be synchronized with lasers operating at up to 100 MHz rate. The pulse picker MP1 can select pulses at up to 600 kHz repetition rate and be synchronized with lasers generating pulse trains with up to 60 MHz repetition rate.

The ModBox-OPP optical pulse picker allows to pick and optionally shape any sub-nanosecond pulse pattern or pulse sequence in an incoming pulse train. It acts as a fast gate with low insertion loss and high extinction from 30 dB to above 55 dB with high stability over time, and with user-adjustable optical pulse duration and optical pulse train repetition rate (when pre-scaler option is embedded).

SHIPS TODAY: Pulse Picker is a synchronization tool for driving external modulation devices such as EOMs, AOMs or SOAs in a pulse-picking mode of operation. It has been designed to work with low level electrical or optical input pulse power like typically the signal coming from a photodiode. It includes 3 pulse picking modes (frequency divider, external triggering & high frequency clock, burst shaping). The Pulse Picker board includes a software-adjustable input voltage level threshold and an (optional) photodiode. This board also includes a special AWG function synchronized with the input signal to perform burst shaping of mode-locked lasers.

NEW: A turn-key pulse-picker solution is now offered covering the full wavelength range between 700 and 1750 nm. It includes the synchronization board described above with our high performances AOMs and drivers.
