Page 6: Laser Safety
1.4.2 Laser Class This PILAS laser system is classified as class 3B laser product according to IEC 60825-1:2014 during all procedures of operation. Class 3B laser systems require wearing certified laser safety glasses. -
Page 7: Label Location
1.4.4 Label Location The shown laser head and labels are samples: Warning label for laser radiation is attached on top of the laser head near the laser emission aperture as shown in the diagram. Laser aperture label is attached on top ... -
Page 8: Introduction
Repetition rates of up to 40 MHz, very low jitter and different triggering possibilities make the PILAS a flexible and reliable system suitable for a wide range of applications. -
Page 9: Operation
3 Operation The following chapters describe controller settings. Nothing needs to be adjusted on the laser head to start operation. 3.1 Installation Set up controller and laser head in stable position. Connect the power supply cable to the controller (100V - 240V, 50Hz - 60Hz). -

11. Power LED, green 3.2 Controller button/rotary knob The digital control unit of the PILAS is operated by four keys UP, DOWN, MODE, ON and rotary knob (see image). You can select the different menus by pressing MODE keys. The UP and DOWN keys are for selections within the menus. -
Page 11: Remote Control
3.3 Remote Control Only one of the USB or the RS232 interfaces should be connected and used. Connecting via computer RS232 COM Port will not require any drivers. Connecting via USB will require the installation of a virtual com port chip set driver (VCP) from FTDI. The controller will appear as virtual COM port afterwards. Properties Connection UART interface support 8 data bits, 1 stop-bit... -
Page 12: Start With Remote Software Pilas Serial Console
3.3.5 Start with remote software PILAS Serial Console You can download a simple serial console for sending commands and receiving the output on the NKTP support website (description or look can change): This software is available for Windows in a 64 and 32 bit version. -
Page 13: Controller Lcd Menu
3.4 Controller LCD Menu The following adjustable laser parameters will be set by software menu: pulse repetition rate / frequency TUNE (pulse amplitude and width) Temperatures (only in debug mode) CW mode (only if ordered) Trigger methods a) internal 25Hz to 40 MHz b) external single shot to 40 MHz ... -
Page 14: Tune Setup
With the UP and DOWN keys, you can navigate within the setup menu. The selected menu is marked by “<” sign on right side. This is valid also for the next menus. For switching to desired menu press MODE button. The following menus are accessible from here: Main Menu <... -
Page 15: Frequency Setup
3.4.5 Frequency Setup Figure 17 Frequency menu The maximum adjustable frequency can be found in the test report or purchase information (40MHz standard). In the second row you can select between “coarse” and “fine” frequency resolution for internal triggering. Selection is done with the rotary knob. Mode coarse: With this option the frequency is adjusted in the third row in predefined steps. -
Page 16: Cw Mode
We recommend checking the controller trigger output signal because the trigger output is linear to the signal the laser diode is seeded with. Optimize the trigger threshold and (if possible) amplitude until the trigger output is clean and stable (no double or multiple pulses within a period). The impedance for all BNC plugs is 50. -
Page 17: Optical Head
4.1 Handling and Adjustment The following chapters describe the main optics shown in the picture above that can be used in conjunction with PILAS-systems. You will find the optics used for your system in the PILAS-test report attached to the manual. -
Page 18: Fiber Coupler (Removable)
4.2.2 Fiber Coupler (removable) The “FC” option is delivered with a fiber coupling unit and a single or multimode mode fiber attached to it as standard. The single mode fiber can be PM fiber (polarization maintaining) or standard single mode fiber. -
Page 19: Pilas Optical Specifications
The laser beam is linear polarized with a ratio of 100:1 or 20dB. The direction of polarization is parallel to the bottom/table plane and perpendicular to propagation axis (red arrow). The figure shows the collimated elliptical output beam of PILAS (blue ray) and the direction of polarization (red arrow). Figure 26 Polarization 4.4.3 Peak Power Calculation... -
Page 20: Timing Jitter
4.4.4 Timing Jitter The measured timing jitter reflects fluctuations of the optical pulse arrival time (at 50% amplitude) in reference to the controller electrical trigger out signal (from which also the optical signal is generated inside the laser head). be the measured time deviation from the ideal optical pulse rising flank position for measurement (sampling oscilloscopes... -
