Beam Shape and Fibre Coupling
All laser heads emit a collimated elliptical beam with typical dimensions of 1.5 × 3.5 mm. They can be optionally fitted with single mode, polarisation maintaining single mode or multi mode optical fibres through appropriate fibre couplers. Different fibre connectors at the fibre output are available (FC/PC, FC/APC and SMA). For details, please see the corresponding webpage.
Available wavelengths (pulsed mode, LDH-P Series)
These laser heads can only be driven either by the PDL 800-B, PDL 800-D, PDL 808 "Sepia" or PDL 828 "Sepia II" driver units.

*pulse width independent from selected power level
**not suited for fibre coupling
Option "B": High Power version
Option "C": Laser head with thermoelectric cooler, mandatory for some laser heads, optional for all other laser heads
Option "M": Transversal multi mode structure, reduced coupling efficiency into single mode fibres
Option "F": Laser head emitting divergent beam from FC/APC fibre coutput connector
All measurements may be subject to a 10% calibration error.
The two power adjustment levels specified here refer to the same laser head. These levels can be adjusted using the corresponding driver (PDL 800-B, PDL 800-D, PDL 808 or PDL 828). The 'Low' adjustment is the best choice for shortest pulses and is usually reached close to the lasing threshold. The 'High' adjustment is used to achieve highest pulse power at moderate pulse length and corresponds to the maximum intensity setting of the driver.
Available wavelengths (dual mode: cw and pulsed, LDH-D Series)
These laser heads can only be driven by the PDL 800-D or the PDL 828 "Sepia II" driver.
