Picosecond laser system PT403

solid-statetunablefor spectroscopy

The PT403 series is a tunable wavelength picosecond laser system that integrates a 1 kHz repetition rate DPSS pump laser and an optical parametric generator into a single housing, providing tunable output from 210 to 2300 nm in one compact unit. This design results in a nearly twice smaller footprint, shorter installation time, improved stability, and substantial user benefits compared to systems with separate laser and OPO units.

Features

• Tuning range: 210–2300 nm
• Motorized hands-free tuning
• High pulse energy at 1 kHz rates
• Diode pumped solid state design
• Narrow linewidth: < 9 cm⁻¹
• Remote control via keypad
• PC control
• Optional streak camera triggering pulse with < 10 ps rms jitter
• Turn-key operation
• Air cooled – external water supply is not required
• Low maintenance costs

Applications

• Time resolved fluorescence (including streak camera measurements), pump-probe spectroscopy
• Laser-induced fluorescence
• Infrared spectroscopy
• Nonlinear spectroscopy: surface-SH, Z-scan
• Other spectroscopic and nonlinear optics applications

Benefits

• Better long term stability (compared with layout where laser and OPO are in different units)
• Higher safety – all beams are in the box
• Shorter installation time
• Almost twice smaller footprint

Description

• All-in-one box solution with all components in a single compact housing, eliminating misalignment risks between separate units.
• Employs industry and market-tested solutions for reliability.
• Pump laser is based on Ekspla PL2210 series diode-pumped, air-cooled, mode-locked Nd:YAG laser.
• Optical parametric generator is based on PGx03 picosecond optical parametric amplifier systems, with fully automatized and microprocessor-based control for precise wavelength tuning.
• Produces low divergence beams with moderate linewidth (typically < 9 cm⁻¹) at ~20 ps pulse duration.
• Versatile, cost-efficient tool for scientific research in time-resolved fluorescence, pump-probe spectroscopy, laser-induced fluorescence, infrared spectroscopy, and more.

Simple and Convenient Laser Control

• Operable from master device or PC via USB (VCP, ASCII commands), RS232 (ASCII commands), LAN (REST API), or WLAN (REST API), depending on system configuration.
• Remote control pad with backlit display for easy operation even with laser safety glasses.

• Communication interfaces:
  • USB: virtual serial port, ASCII commands
  • RS232: ASCII commands
  • LAN: REST API
