| AXIS-SV is a compact streak camera with picosecond resolution. Its MHz averaging capability is well suited for :
|
Streak tube |
Photonis 900 family tubes: These compact sealed tubes provide a picosecond temporal resolution and its screen is well-suited for CCD readout. |

Operation modes |
|
| Normal sweep | The sweep starts out of the screen, crosses the whole screen and ends outside the screen. |
| Timing mode | The sweep starts in the screen and ends also the screen. It is used to synchronize the streak camera to the event. |
| Focus mode | A static voltage is applied to position the trace close to the center of the screen. The sweep trigger is disabled. This mode is used to adjust the incident light into the streak camera. |
General |
|
| Electrical input | Universal AC, 110-240V, 50-60 Hz |
| Certification | CE |
| Tests and Calibration | Before shipping, each system is tested on a femtosecond laser at the Advanced Laser Light Source (Canada) |
| Installation and Training | A qualified engineer is sent to your laboratory to install the system and train users |
Options |
||
| Blanking circuits | With the blanking option, streak tube is blocked during the time the signals sweeps back to its start position. This feature is required when the optical signal lasts longer than the sweep range. | |
| Remote control over Optical Ethernet | Web-based user interface to operate system via optical Ethernet 1 Gb/s (1000 Base SX) on 2 SMA 905 connectors (or other common fiber optics standards). | |
| Laser-triggered sweep unit for CPA lasers |
Because of its sub-picosecond jitter, this unit allows the analysis of ultrafast events at repetition rates up to 10 kHz while conserving the excellent spatial and temporal resolution of the AXIS streak camera. This is the ideal tools ultrafast spectroscopy with large dynamic range and high signal-to-noise ratio It requires about 100 µJ per laser pulse. |
Only a fraction of the laser energy is taken to trigger photoconductive switches. This allows signal averaging over a large number of laser shots. |
The signal is averaged over 1 million shots (~ 20 minutes) and time resolution is still subpicosecond. |
