Quantel launch Pizzicato picosecond Nd:YAG laser
26 September 2008
The Pizzicato is an all-solid state, mode-locked picosecond Nd:YAG laser providing up to 100mJ in a 35ps pulse at 1064nm with high stability
Based on a unique design, the Pizzicato features low jitter, high pulse-to-pulse stability with synchronization capability. The all solid state design is free from the constraints of previous designs that used liquid saturatable absorbers whilst maintaining short pulse durations of 35ps.
|
The Pizzicato’s mode-locking device forces all the longitudinal modes of the laser cavity to oscillate in phase, allowing the resonator to generate ultrafast (picosecond) pulses. |
|
The picosecond pulses result from the rotation of the polarization by frequency back conversion in a non-linear crystal. This totally passive device produces a wave train made up of several ultrafast pulses and is combined with a double-pass Pockels cell pulse picker system. Together these components produce stabilized ultrafast pulses precisely separated by a few nanoseconds. |
|
The pulse picker generates a synchronization signal allowing the laser to be synchronized with other apparatus and produces excellent energy stability, whilst the second pass increases the energy, power contrast and aids stability & reproducibility. |
Only the highest quality mechanical, electronic, and optical components have been used in the Pizzicato to ensure high performance, trouble-free operation and ease of use throughout the laser’s lifetime. These include a carbon fibre resonator support structure with floating fasteners to efficiently absorb any differential expansion and an optical isolator situated between the preamplifier and amplifier to protect the oscillator and mode-locking module against back reflections.
