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.
Hands-free tuning: motorized for the entire tuning range
Linewidth <3 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
Fast wavelength scan (sweep)
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 laser can be operated from a master device or a personal computer using various interfaces. Depending on the system configuration, control is available via the USB interface (REST API over RNDIS or VCP with ASCII commands), the RS-232 interface (ASCII commands), the LAN interface (REST API), or from the remote control pad with a backlit display that remains easy to read even while wearing laser safety glasses.

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 3500 nm for PT501 units for basic system without options.
Beam diameter is measured at the 1/e2 level.
At 3000 nm, Full angle measured at the FWHM point
With respect to TRIG1 OUT pulse. <10 ps jitter is provided with PRETRIG option.
