Timing Generator for Synchronizing Laser Systems

The TG10 is a timing generator dedicated for triggering and synchronization of laser systems and laser components, for example for Pockels cells and pulse pickers, flash lamps and data acquisition systems.

Description 

Features:

  • Ultra-stable internal clock 0.2 ppm
  • Precise delay control in range 2 ns to 150 ms
  • 25 ps timing resolution
  • Hi-accuracy synchronization to the external pulse train
  • DAC output
  • Frequency divider
  • Frequency divider for photodetectors
  • Measurement of Optical clock frequency, Triggering frequency, and Delay

Applications:

  • Passive or active mode locked, Q-switched lasers, pulsed or QCW
  • Data acquisition system triggering
  • General purpose pulse generator
  • Precise system clock source
  • Laser pulse train converting to the clean clock source
  • All functions listed above simultaneously at once!

The TG10 is a timing generator dedicated to the synchronization of laser systems and laser components: Pockels cell drivers, acousto-optical modulator drivers, laser diode and flash lamp drivers, detectors, data acquisition systems, laser pulse pickers, etc. The TG10 is designed to create up to 8 delayed output sequences precisely synchronized to the internal or external clock. A photodetector or electrical signal can be used as the input source to be synchronized with.

The following are the key features of the TG10 module in addition to standard pulse generator:

  • Ability to lock to an external clock source, usually photo-diode pulse train. The triggering system is locked to the laser oscillator then, and trigger time is always in phase with the optical pulse.
  • Instant switch between two configurations in delay blocks. Burst counter, gate input, frequency divider, or software commands may serve as the configuration switching signal sources. Configuration switch is used to control optical pulse pickers (EOM or AOM) in a highly flexible manner.
  • Low jitter sync pulse output is used for high-speed acquisition systems like streak camera triggering. The typical jitter is 3...5 ps to the optical pulse.
  • Control connector. The software-controllable multiplexer may divert any of the output signals to this connector to sniff what is on other connectors without disturbing them.
  • Clock output: 1:1, 1:2 frequency.
  • Up to 4 pulse outputs can be combined to single signals by OR, AND, NOT logical operations.
  • DAC output, controlling, e.g. AOM pass though.

TG10 has the following input and output channels:

  • OUTx - five digital general-purpose output (4.5V @ 50 Ω)
  • AN OUT - analog output with 12-bit resolution (1V @ 50 Ω)
  • COM TRIG - common trigger output. Configurable source (2.5V @ 50 Ω)
  • PRE TRIG - precise trigger output channel. Configurable source (>1.5V @ 50 Ω)
  • GATE IN - configuration switch and burst control input. (LVTTL, tolerates 5V. 0.2 mA pull-down)
  • SYNC IN - trigger input for DC to 20 MHz frequencies. (LVTTL, tolerates 5V. 0.2 mA pull-down)
  • CLK IN - clock input for 10 MHz to 100 MHz frequencies. (0.5V to 3.3V @ 50 Ω pk-pk, sine or pulses)

The timing generator can be used as a standalone unit with a touch screen interface (TG10) or installed as an optional add-on PCB board (SY4000). The TG10 device has an LCD touch screen for the manual control and a tunable knob for the adjustment of selected values set on the touch screen. Instructions of required actions are always displayed at the bottom of the screen. Besides, the timing generator has a digital control interface via CAN bus. Communication protocol with description for CAN is provided on request. CAN to USB converter is also available.
