PT501 series
Single Housing Mid-Infrared Tunable Picosecond Laser System
PT501 series laser systems integrate a picosecond optical parametric oscillator (OPO) and a pump laser in a single compact housing. Mounting the components on the same frame provides a robust solution. It makes laser installation shorter, improves long-term stability, and reduces maintenance costs.
Features
- Tuning range 2300 – 16000 nm (4345 – 625 cm‑1)
- Hands-free tuning: motorized for the entire tuning range
- Linewidth <4 cm‑1 in the entire tuning range
- Repetition rate 100 Hz
- Air cooled – external water supply is not required
- Beam direction stability in the entire tuning range
- Single housing: integrates a pump laser and OPO in a single housing
- PC control via USB (virtual COM port), RS232, LAN using REST API commands
Applications
- Infrared spectroscopy
- SFG (sum frequency generation spectroscopy)
Description
PT501 series laser systems integrate a picosecond optical parametric oscillator (OPO) and a pump laser in a single compact housing. Mounting the components on the same frame provides a robust solution. It makes laser installation shorter, improves long-term stability, and reduces maintenance costs.
Fast and fully automatic wavelength tuning is achieved by advanced microprocessor control. The wavelength tuning elements are mounted on precise closed-loop micro-stepping motors. The temperatures of the nonlinear crystals are controlled by precise thermo-controllers. No additional manual adjustment of the laser system is needed.
For customer convenience the system can be controlled by a keypad and/or any controller running on any OS using REST API commands. Variety of interfaces USB, RS232, LAN, WLAN (optionally) ensures easy control and integration with other equipment.
