PGx11 series optical parametricdevices employ advanced designconcepts in order to produce broadly
tunable picosecond pulses with nearly
Fourier-transform limited linewidthand low divergence. High brightness
output beam makes the PGx11 series
units an excellent choice for advanced
spectroscopy applications.
Optical layout of PGx11 units
consists of Synchronously pumped
Optical Parametric Oscillator (SOPO)
and Optical Parametric Amplifier(OPA). SOPO is pumped by a trainof pulses at approx. 87 MHz pulse
repetition rate. The output fromSOPO consists of a train of pulses

with excellent spatial and spectral
characteristics, determined by theSOPO cavity parameters.
OPA is pumped by a single pulse
temporally overlapped with SOPO
output. After amplification at SOPO
resonating wavelength, the PGx11
output represents a high intensity
single pulse on top of a low-intensity
train, while in all other spectral ranges(idler for PG411 and PG711, signal for
PG511, also DFG stages) only a single
high intensity pulse is present.
Three models designed forpumping by up to the 3rd harmonic ofNd:YAG laser are available.

PG411

Model has a tuning range from 410 to 2300 nm and is optimized for providing highest pulse energy in thevisible part of the spectrum. When combined with an optional Second Harmonic Generator (SHG) and Sum
Frequency Generator (-DUV), it offers the widest possible tuning range – from 193 to 2300 nm.

PG511

Model has a tuning range 2300 – 10000 nm. PG411 and PG511 models are designed to be pumped by PL2230
series lasers with a 50 Hz pulse repetition rate.

PG711

Model has 1 kHz pulse repetition rate and uses DPSS mode‑locked laser of the PL2210 series for pumping.
When pumped with pulses of 90 ps duration, linewidths of less than 1 cm⁻¹ were measured in the spectral
range up to 16 µm, which makes this device an excellent choice for time-resolved or nonlinear infrared
spectroscopy.
