kHz repetition rate picosecond OPG PGX03 series

PGX03 series OPGs are excellent choice for researchers who need picosecond tunable sources from UV to mid IR. Featuring 1 kHz repetition rate and due to the unique broad tunability range these devices are a very attractive and cost-efficient alternative to other tunable laser radiation sources.

Features

  • Picosecond pulses at 1 kHz pulse repetition rate
  • Hands-free wavelength tuning
  • Spectral range of 230 nm to 16 000 nm
  • Narrow linewidth <6 cm-1
  • Low divergence
  • Remote control via keypad
  • PC control using USB (RS232 is optional) and LabView™ drivers

Applications

  • Time resolved pump-probe spectroscopy
  • Laser-induced fluorescence
  • Infrared spectroscopy
  • Nonlinear spectroscopy: vibrational-SFG, surface-SH, CARS, Z-scan
  • Other laser spectroscopy applications

PGx03 series optical parametric generators (OPG) are designed to be pumped by 1 kHz mode-locked lasers with 1 W average power.
An excellent choice is the PL2210A series mode-locked picosecond laser from EKSPLA.
The optical design is optimized to produce low divergence beams with moderate linewidth (typically 12 cm-1) at approximately 20 ps pulse duration. Due to the unique broad tunability range of 210 to 16 000 nm these devices are an excellent choice for many spectroscopic applications.
Upon request the optical layout can be easily modified for pumping by other mode-locked lasers with high pulse energy or longer pulse duration.
Three models designed for pumping by up to the 3rd harmonic of Nd:YAG laser are available.
PG403 model has a tuning range of 410 nm to 2300 nm and is optimized for providing highest pulse energy in the visible part of the spectrum. When combined with an optional second harmonic generator (SHG), it offers the widest possible tuning range – from 210 nm to 2300 nm.
PG503 model has a tuning range of 700 nm to 2300 nm and highest pulse energy in the near-IR spectral range. PG503 is a cost-effective alternative to the narrow-band mode-locked Ti:S lasers.
PG703 model is targeted for infrared spectroscopy applications. The tuning range is from 1450 nm to 4450 nm and with an optional difference frequency generator (DFG) stage it can be extended to 16 000 nm.
Microprocessor based control system provides automatic positioning of relevant components for hands free operation. Nonlinear crystals, diffraction grating and filters are rotated by ultra-precise stepper motors in the microstepping mode, with excellent reproducibility.
Precise nonlinear crystal temperature stabilization ensures long-term stability of generated wavelength and output power.
For customer convenience the system can be controlled using a user-friendly remote control pad or through USB interface (RS232 is optional) from a personal computer (PC) using supplied LabView drivers.
Available standard models are summarized in a table on the page below. Please inquire for custom-built versions.
