1. Mount the laser head as needed using the supplied ECM225 clamps and either imperial or metric screws. After screwing the ECM225 clamps to any convenient base or post, such as one of Thorlabs’ TR series optical posts, snap the clamps on to the bottom side of the NPL housing. Firmly tighten the clamps using the locking screws.
Page 18: Chapter 4 Operation
Control and Oscillators provide internally-generated trigger signals, which make it possible for the B versions to produce stable trains of nanosecond pulses without an external trigger. Figure 8 Block Diagram of the NPL Series Laser Head Rev. J, March 20, 2025 Page 15...
Page 19: Power
The shorting device (interlock pin) installed in all units shipped from Thorlabs performs this function. Leave the shorting device installed unless using an external safety circuit or other type of remotely controlled switch to enable laser output.
Page 20: Pulse Widths And Repetition Rates
Pulse Widths and Repetition Rates NPL series lasers with Item # suffix A and C require a user trigger input to the SMA connector on the back panel. The NPL64A laser supports rates up to 10 MHz. The C version supports rates up to 50 kHz. The slowest supported edge transition time for the trigger signal is 1 ms.

Do not use acetone, chemical solvents, or harsh cleaning solutions, and do not spray cleaning solutions directly onto the unit. See Chapter 6 for advice on cleaning the lens. The NPL does not contain any user-serviceable components. If malfunctions occur, please contact Thorlabs’ technical support ( ).
Page 22: Chapter 6 Troubleshooting And Repair
Contact Thorlabs for more information. Waste treatment is your own responsibility. “End of life” units must be returned to Thorlabs or handed to a company specializing in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site. It is the user’s responsibility to delete all private data stored on the device prior to disposal.
