Tunable Burst-in-Burst Option for PHAROS — BiBurst
Now the PHAROS laser available from Light Conversion has an option for tunable GHz and MHz burst with burst-in-burst capability — called BiBurst. The distance between burst packet groups is called the nanosecond burst (N). The picosecond burst (P) is the distance between sub-pulses in the group. The image below illustrates the difference between the single pulse mode and burst pulse mode.
In the single pulse mode, the RA amplifies one single pulse at some repetition rate. In burst pulse mode, however, the output consists of several picosecond burst packets (three packets in the example above). Equal time periods (15.5 ns in the example) separate these packets. Each packet can contain a number of sub-pulses (six in the example above). These sub-pulses are also separated by an equal time period between pulses (200 ps in the example). This nanosecond burst has the same repetition rate as the single pulse mode, 50 kHz.
The figure below shows the burst shape modes available:
The next figure shows the burst pulse train envelope configurable → decreasing, quasi-flat, increasing:
The burst option requires a different PHAROS enclosure: PH-666 (i-OPA, Burst) size: 360 x 688 x 212 mm.
