Controlling multiple lasers in one window with Integrated Optics, UAB
software isn’t possible. It is only an example for integrators.

TTL Modulation
TTL stands for transistor-transistor-logic. In the context of laser modules,
TTL modulation means a convenient and standardized method for lasers’
modulation. The voltage tolerance for TTL inputs of all MatchBox lasers
is +5 VDC (+ 3.3 VDC compatible).
Programmable pin configuration and modulation speed differ between
DPSS and direct diode lasers:
- for DPSS type lasers, to allow TTL modulation, programmable pin has
to be set to ‘P4’ and modulation speed in both APC and ACC operation
modes is up to 500 Hz (electronics version: 11.4.XX).
- for direct diode lasers, programmable pin has to be set to ‘P0’ and
modulation speed in ACC operation mode can reach up to 10 MHz, in
APC operation mode only up to 1 kHz (electronics version: 1.3).
To use TTL modulation, modulation inputs should be connected to ‘TTL’
and ‘GND’ pins.
