Picosecond diode lasers

[psec/psec-driver.jpg][psec/psec-driver2.jpg]

We are offering a wide range of picosecond lasers with pulse frequency up to 50 GHz and duration from 2 ps. Laser power supply source can be produced in cabinets and with control units defined by customer requirements. The device can be equipped with several lasers with various wavelengths and impulse parameters.

In the mode of non-periodic pulse running, pulse frequency can be regulated from single start up to 800 MHz with the use of the internal or external trigger, and in the mode of periodic recurrence it can be within a range from 200 MHz to 50 GHz.  In order to reach the periodic impulse sequence, such methods as Q-switching and mode-locking are applied. Apart from generating the picosecond impulses, it is possible to get also rectangular impulses with duration from 3 ns up to continuous mode.

The radiation output via single-mode or multimode optical fiber is possible.  As an option external laser module with collimated beam is also possible.
