Picosecond pulsed laser at 1950 nm
- Picosecond pulsed laser at 1950 nm
- Average power > 4 W
- Pulse energy up to 1.2 μJ
- Pulse width typ. 100 ps
- Externally triggerable from 62.5 kHz to 40 MHz
- Internal oscillator 0.25 to 4.0 MHz
The PiQus 2000 is a stand-alone, computer controlled ps-pulsed laser source achieving µJ pulse energies at very high repetition rates (up to 4 MHz). The device is compatible to laser class 4 standards and can be operated in a safe and easy manner: laser beam output is realized via an optical isolator attached to a single mode delivery fiber. The entire laser system is air cooled, thus does not required any water cooling.
Variable repetition rates up to 40 MHz
The PiQus 2000 can be operated at various freely adjustable repetition rates. Repetition rates can be selected either using an internal oscillator, providing six fixed user-selectable repetition rates between 250 kHz and 4 MHz. Alternatively, the PiQus lasers can be externally triggered at any repetition rate ranging from 62.5 kHz to 40 MHz. This unique feature allows synchronization of the PiQus 2000 with other devices.
Constant pulse energy with pulse width of 100 ps
The output pulse energy is electronically controlled and remains constant at 1 µJ over a wide range of repetition frequencies (62.5 kHz and 4 MHz). This even works at external triggering and allows for e.g., frequency sweeps. At repetition rates above 4 MHz, the pulse energy decreases gradually down to 0.1 µJ at 40 MHz.
The output pulse width depends on the output power and is typically around 100 ps (FWHM). Each pulse is accompanied by a corresponding timing optimized synchronization signal, which can be used to trigger other components such as timing electronics.
Full computer control via easy to use software
The PiQus laser is completely computer controlled by an easy to use graphical user interface (GUI) for Windows. The device is plug and play and connected via USB to the PC. The software allows controlling the pulse repetition rate, triggering mode (internal or external) and laser intensity. Different settings can be pre-defined and saved for an easy change of configurations. A library for custom programming is also provided and allows access to all functions of the PiQus from, e.g., LabView or other programming languages.
