Nonlinear Spectroscopy Systems

PL2210 series diode-pumped,
air-cooled, mode-locked Nd:YAGlasers provide picosecond pulses at akilohertz pulse repetition rate.
Short pulse duration, excellent
pulse-to-pulse stability, superior beam
quality makes PL2210 series diodepumped picosecond lasers well suitedfor many applications, including
material processing, time-resolved
spectroscopy, optical parametric
generator pumping, and other tasks.

Flexible design
PL2210 series lasers offer a numberof optional items that extend thecapabilities of the laser.
A pulse picker option allows control ofthe pulse repetition rate of the laser
and operation in single-shot mode.

The repetition rate and timing ofpulses can be locked to an external
RF source (with –PLL option) orother ultrafast laser system (with–FS option). The laser provides atriggering pulse for synchronizationof the customer‘s equipment. A low
jitter SYNC OUT pulse has a lead up
to 500 ns that can be adjusted in~0.25 ns steps from a PC. Up to 400 μs
lead of triggering pulse is available asa PRETRIG feature that is designed toprovide precise, very low jitter triggerpulses for a streak camera.

Built-in harmonic generatorsMotorised switching of wavelengthfor PL2210A. Non-linear crystals
mounted in temperature stabilizedheaters are used for second, third andfourth high spectral purity harmonicgeneration.

producing up to 40 mJ per pulse
at 1064 nm▶ Beam profile improvement using

advanced beam shaping system▶ Hermetically sealed DPSS masteroscillator▶ Diode pumped regenerative

amplifier▶ Air-cooled

Innovative design
The heart of the system is a diodepumped solid state (DPSS) master
oscillator placed in a sealedmonolithic block, producing highrepetition rate pulse trains (87 MHz)
with a low single pulse energy ofseveral nJ. Diode pumped amplifiers
are used for amplification of thepulse to 30 mJ or up to 40 mJ
output. The high‑gain regenerative
amplifier has an amplification factor
in the proximity of 10⁶. After theregenerative amplifier, the pulse
is directed to a multipass power
amplifier that is optimized for efficient
stored energy extraction from theNd:YAG rod, while maintaining anear Gaussian beam profile and low
wavefront distortion. The output
pulse energy can be adjusted inapproximately 1% steps, whilepulse‑to-pulse energy stability remains
at less than 0.5% rms at 1064 nm.
Angle-tuned KD*P and KDP crystals
mounted in thermostabilised ovens
are used for second, third, and fourthharmonic generation. Harmonic
separators ensure the high spectralpurity of each harmonic guided todifferent output ports.

REV. 240116

Built-in energy monitors continuously
monitor output pulse energy. Datafrom the energy monitor can be seenon the remote keypad or on a PC
monitor. The laser provides triggering
pulses for the synchronisation of yourequipment. The lead of the triggering
pulse can be up to 500 ns and is user
adjustable in ~0.25 ns steps from apersonal computer. Up to 1000 μs
lead of triggering pulse is available asa pretrigger feature. Precise pulse
energy control, excellent short-termand long-term stability, and a 50 Hz
repetition rate makes PL2230 series
lasers an excellent choice for many
demanding scientific applications.
