Picosecond laser system PGx01

ultravioletmid-infraredbroadly tunable

The PGx01 series is a high energy, broadly tunable picosecond optical parametric amplifier (OPA) designed for advanced spectroscopy and research applications. Travelling Wave Optical Parametric Generators (TWOPG) provide ultra-fast, tunable coherent light sources spanning from the ultraviolet (UV) to the mid-infrared (mid-IR) spectrum, making them ideal for a wide range of scientific investigations.

Features

• Ultra-wide spectral range from 193 to 16,000 nm
• High peak power (>50 MW) suitable for non-linear spectroscopy applications
• Narrow linewidth <6 cm⁻¹ (for UV < 9 cm⁻¹)
• Motorized hands-free tuning in 193–2,300 nm or 2,300–16,000 nm range
• PC control and remote control via keypad

Applications

• Nonlinear spectroscopy: vibrational-SFG, surface-SH, Z-scan
• Pump-probe experiments
• Laser-induced fluorescence (LIF)
• Other laser spectroscopy applications

Description
The PGx01 series consists of several functional modules: optical parametric generator (OPG), diffraction grating-based linewidth narrowing system (LNS), optical parametric amplifier (OPA), and an electronic control unit. The OPG module generates parametric superfluorescence (PS), with spectral properties determined by the nonlinear crystal and varying with wavelength. For narrowband radiation, the OPG output is narrowed by the LNS to 6 cm⁻¹ and used to seed the OPA.

Output wavelength tuning is achieved by adjusting the angle of the nonlinear crystal(s) and grating, with precise stepper motors and computerized control ensuring exceptional wavelength reproducibility. Nonlinear crystal temperature stabilization provides long-term output stability. Built-in photodetectors monitor pump pulse energy to protect the crystals, and the control unit alerts if energy exceeds preset values.

The system can be operated via master device or PC (USB, RS232, LAN) or from a remote control pad with a backlit display, suitable for use with laser safety glasses.
