Pulse pickers
for Yb, Nd, and Ti:Sapphire lasers
Pulse pickers are optical devices that work as high-speed optical gates. Electro-optic pulse pickers are based on the Pockels effect, which enables the rapid control of polarization of light pulses by applying a carefully timed, fast high-voltage signal to a birefringent crystal.
Applications
- Selection of single laser pulses from a pulse train
- Lowering pulse repetition rate of mode-locked lasers
- Seeding and cavity dumping in regenerative amplifiers
- Q-switching
- Pulse cleaning in chirped pulse amplification
- Pulse slicing
- Micromachining and material processing
- Time-resolved spectroscopy and imaging
Advantages
- Single-box optical head with complete prealigned optical scheme
- Built-in Faraday isolator to prevent mode-locking breakdown
- Adjustable to any input polarization (half-wave plate included)
- 4-channel delay generator with locking and timing electronics
- Compatible with most commercial mode-locked laser oscillators
- Optional core version with a Pockels cell and built-in high-voltage driver for OEM integration
PP-S series pulse pickers are designed to select individual laser pulses from a high-frequency laser train.

PP-A series pulse pickers generate a quasi-rectangular optical gate window of adjustable width to control femtosecond regenerative amplifiers or Q-switched lasers, or to form bursts of laser pulses.
