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 from 210 to 16000 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 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.|
|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.|
|PG703||Model is targeted for infrared spectroscopy applications. The tuning range is from 1400 to 4450 nm and with an optional Difference Frequency Generator (DFG) stage it can be extended to 16000 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.
