By chopping a laser pulse as it builds up inside a “Q” switched cavity it is possible to produce a “Q” switched output pulse considerably shorter than the normal “Q” switched pulse. Del Mar Photonics Pismo pulse picker Control and supply unit oscilloscope is not included. This requirement is normally required to stop the build up of Amplified Stimulated Emmision.
The electronic driver of a pulse picker may fulfill additional functions. The blocked pulses do not necessarily constitute a strong energy loss since the average power of the seed laser may be small compared with the average output power of the amplifier, and the remaining average power can be sufficient for saturating the amplifier. Half wave switching requires twice the voltage of quarter wave switching.
The second is relatively low rep rate with a single pulse lockels on single polarization.
Pulse Pickers and Regen Systems. Some typical applications of a pulse picker are described in the following: In gep systems this effect is simply overcome by increasing the amplitude of the applied pulse to greater than that required for DC induced retardation.
It is completely modular in construction, with plug-in units which can be up-gradeable and field replaceable to provide quick turnaround service. Stud or pin connections are available.
DQ High Repetition Rate Pockels Cell Driver for Q-Switching
It is suitable for single pulse selection from train of femtosecond or picosecond pulses. Pulse picking is the selecting of a pocckels from a mode locked train.

Ability to operate at high pulse repetition rates makes this driver perfect fit for most of diode-pumped nanosecond lasers. Fast rise times systems for Regenerative amplifiers. Fast HV less than 7 ns edge ensures excellent pre- and post-pulse contrast.
For various reasons see belowit is often necessary to pick certain pulses from such a pulse train, i. The peak voltage should be timed to hign pulse. For obtaining high pulse energies in ultrashort pulses, it is frequently necessary to reduce the pulse repetition rate. Find more supplier details at the end of rqte encyclopedia article ceol, or go to our.
HV pulse amplitude up to 4 kV DQ Series high repetition rate Pockels cell driver has been designed for use in mode-locked lasers for cavity dumping or for cavity Q-switching of solid-state nanosecond lasers. To overcome this some Q switch drivers offer the possibility to switch beyond ground, i.
The use of a three electrode cell allows complete decopupling of a pair of drivers without increasing the number of optical surfaces.
DQ High Repetition Rate Pockels Cell Driver for Q-Switching | Eksma Optics
Longitudinally driven cells offer the highest performance but require the highest voltages. Extra cavity pulse pocke,s is not nearly as efficient as intra-cavity pulse shaping or pulse compression by, for example, Brillouin back scatter.
Only one edge of the pulse is important. The price of a driver scales like the peak power voltage squaredthe repetition rate and the reciprocal of the risetime. Quantum designs many other devices and systems, both standard and custom made. Pockels cell driver should be mounted into dielectric box should be ordered separately providing electrical insulation.
Typical systems use many small pulsers, the outputs of which are added with a programmable timing and possibly programmable amplitude.
