The CPDL-M and CPDL-S Series from PicoQuant consists of a range of laser heads solutions for OEM integration. These laser heads are based on our well established picosecond pulsed diode laser technologies as used in the LDH Series. The CPDL-M and CPDL-S heads do not require a laser driver from the PDL Series for operation.
However, some (simple) integration work on the customer’s side is needed to provide an electrical power supply. Optionally, a specific CPDL power supply including key and frequency switches can be provided for plug and play operation. These laser heads do not require any adjustment and are delivered with fixed intensity setting (i.e. with fixed pulse shape and pulse energy). The laser heads can be triggered either internally (CPDL-M) at selected repetition rates (typically 40, 20, 10, and 5 MHz) or externally (CPDL-S) at any repetition rate ranging from single shot up to typically 40 MHz.
The model list shown here is non-exhaustive and custom tailored solutions can be realised on request. Feel free to to contact us with your requirements.
Pulse widths down to 20 ps
Pin assignment for the CPDL-M/S SeriesIn general, laser heads from the CPDL Series generate pulses with a temporal width of ca. 100 ps (FWHM). Some models can achieve pulse widths down to 20 ps. The exact temporal pulse width depends on both the laser diode and the intensity level at which it is currently operated. The intensity level of the CPDL-S and CPDL-M heads are set during manufacturing at the level you choose for your application.
Repetition rates
CPDL-M heads are delivered with a fundamental frequency of 40 MHz (80 MHz is available on request for some wavelengths). This fundamental frequency can be divided by a factor of 2, 4, and 8 using a pair of logical levels. CPDL-S heads are delivered with an external trigger input, which can be triggered at any repetition rate between single shot and 40 MHz. For some wavelengths, 80 MHz is available on request. Combining high intensity settings with fast repetition rates can lead to significant heat generation, which needs to be taken into consideration when designing heat dissipation solutions for some diode types. Please ask PicoQuant if you have any question about this.
Fibre coupling and combiner
All laser heads from the CPDL Series can be optionally coupled into a variety of optical fibres (multi-mode, single mode, or polarisation maintaining single mode) via different connector types. We recommend FC/APC connectors for most applications, since they prevent back reflections that can interfere with laser stability. For more details, refer to our solutions for fibre coupling.
Applications
CPDL-M and CPDL-S lasers are suitable for a wide range of applications including semiconductor diagnostics, testing of detectors and cameras, ranging / LiDAR, seeding of amplifiers, material processing, free-space data transmission, fluorescence lifetime measurements, time-resolved refractometry, or as solid state booster to name only a few. They can easily be incorporated into larger systems such as readers, wafer testers, optical devices, or μJ laser systems for micromachining.
