PGx03 Series - Tunable High Repetition Rate OPG Systems

The OPG´s of the PGx03 series are designed for a high repetition rate (1 kHz) and optimised for pumping by PL2210 series lasers. These lasers are an excellent choice for many spectroscopic applications because of the unique wide tunability range from 210 to 2300 nm, the short pulse duration (15 - 20 ps) and the narrow linewidth (down to < 6 cm-1).

Description 

Features

  • Picosecond pulses at 1 kHz pulse repetition rate
  • Hands-free wavelength tuning
  • Tuning range from 210 nm to 2300 nm
  • Narrow linewidth <6 cm⁻¹
  • Low divergence <2 mrad
  • 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, Z-scan
  • Other laser spectroscopy applications

Travelling Wave Optical Parametric Generators (TWOPG) are an excellent choice for researchers who need an ultra‑fast tunable coherent light source from UV to mid IR.

Design

The units can be divided into several functional modules:

  • optical parametric generator (OPG);
  • diffraction grating based linewidth narrowing system (LNS);
  • optical parametric amplifier (OPA);
  • electronic control unit.

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 15 –20 ps pulse duration. Due to the unique broad tunability range from 210 to 2300 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.

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.

 

Model Features
PG503 Model has a tuning range from 700 to 2300 nm and the highest pulse energy in the near-IR spectral range. PG503 is a cost-effective alternative to the narrow-band mode-locked Ti:S lasers.
PG403 Model has a tuning range from 410 to 2300 nm and is optimized for providing the 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 to 2300 nm.

1 ) Due to continuous improvement, all specifications are subject to change without notice. Parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 450 nm for PG403 units, at 800 nm for PG503 units and for basic system without options.

2) Pulse energies are specified at selected wavelengths. See typical tuning curves for pulse energies at other wavelengths.
