Laser Firing System (LFS)
The LFS system has been designed to provide a complete remote operation of a pulsed laser system. The OEL currently has some 10 Laser Firing Systems (LFS) being used world-wide all in conjunction with Lumonics Ruby pulse holographic lasers.
Examples of current customers being:
 | BAe Sowerby, ETH Zurich, EPFL Lausane, Metro Laser California
| The University of Delft & Rolls-Royce Derby. | |
The OEL also uses the LFS to provide a remote computer control its own Nd/Yag and Ruby lasers.
The LFS has the following features:
| It is totally programmable from the keyboard of a computer.
| Using an embedded RISC on-board processor the LFS's firing accuracy is
100n with a jitter of 10ns. | |
Examples of the LFS's Laser Firing Features:
| Fires the laser amplifier and discharge tubes.
| Controls the laser charging voltages.
| Controls the internal and external Pockel cells.
| Sets-up firing delay times.
| Allows a pre-programmed firing sequence to be performed.
| Used to control external devices such as video, photographic or
holographic cameras. | |
Examples of the LFS's Hardware Features:
| Timing accuracy of 100 nsecs.
| Accepts a 5volt TTL signal to fire the laser.
| Provides 6 digital output opto-isolated ports.
| Provides 6 input analogue ports.
| Operates within an industrial environment. | |
