Tunable BiBurst for CARBIDE CB3 Laser Now Available
Now the CARBIDE CB3 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 (15.8 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 (440 ps in the example). This nanosecond burst has the same repetition rate as the single pulse mode, 50 kHz.
The next graphs show the maximum number of P-spaced pulses while N=1 (left) and the maximum number of N-spaced pulses while P=1 (right) versus laser repetition rate. Please note, that selecting a mixed number of pulses reduces the maximum number of pulses.
The following figure shows the burst pulse train envelope configurable → quasi-flat, declining, inclining:
The CARBIDE User App enables the user to quickly set the P and N pulse envelopes by simply moving the sliders on the user interface, as shown below.
Importantly, the burst option for CB3 does not require a different size enclosure. For additional information about Carbide CB3 burst-in-burst capabilities, click here.
