The Thorlabs NPL52B nanosecond pulsed laser systems produce adjustable-duration nanosecond pulses in response to a user-supplied trigger input sent to the Trigger In port on the back panel of the laser head, shown in the image to the right. Pulses may be triggered at rates up to 10 MHz. These lasers also incorporate an internal trigger, enabling repetition frequencies of 1, 5, or 10 MHz. The aspheric lens integrated into the laser head is permanently fixed and factory set to collimate the optical output.

Pulse widths are adjustable from 5 to 39 ns over 16 discrete settings with approximately equal spacing. While the pulse width range of the NPL52B is 520 nm, similar items are available for certain wavelengths between 405 nm and 980 nm. The controls for adjusting the pulse width and repetition rate are located on the back panel. These laser systems include the laser head, a +15 V power supply, a 2.5 mm flathead screwdriver, and two ECM225 clamps for post mounting the laser head.
