VPL

Product catalog summary

Overview: The VPL series of diode lasers are designed for variable width pulse generation ranging from nanoseconds to milliseconds, as well as continuous wave (CW) operation with power outputs up to 60 mW. These lasers are optimized for long photoluminescence lifetime measurements using the Multi-Channel Scaling (MCS) detection method. They are compact, maintenance-free, and user-friendly, with external trigger capabilities allowing integration into various experimental setups.

Key Features:

Optimized for MCS with 14 pre-set pulse widths from 50 ns to 1 ms.
External trigger capability for adjusting pulse width and repetition rate.
Operation in CW mode with spectrally purified output.
Compact plug-and-play design with extremely low RF radiation and optimized collimated beam.

Specifications:

Pulse Widths: 50, 100, 200, 500 ns; 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000 μs.
External Trigger Width Mode: Pulse width and repetition rate defined by external trigger input with a maximum duty cycle of 50%.
Bias Supply: 15 Vdc +/- 5%, 15W (2.1mm DC jack).
Trigger Output: SMA, NIM Standard.
Interlock and Trigger Input: Hirose HR10A-7P-4P(73) with specific pin configurations.
Beam Quality: 10% - 90% knife edge method with beam diameters specified at output aperture and after propagation.
Physical Dimensions: Overall 168 mm length x 64 mm x 64 mm; Collimator tube ø 30 mm x 38 mm.
Weight: 750 g.

Safety and Compliance: The VPL series is classified as a Class 3B laser product, requiring adherence to laser safety regulations to avoid harmful exposure to the beam. The product complies with US federal laser product performance standards and IEC 60825-1:2014.

Customer Support: Available worldwide.

VPL SERIES Adjustable Pulse Width Diode Lasers The VPL series of diode lasers provide variable width pulses in the ns to ms range, as well as CW operation with powers up to 60 mW. KEY FEATURES Optimised for MCS 14 Pre-set pulse widths from 50 ns to 1 ms They are optimised for long photoluminescence lifetime measurements using the Multi-Channel Scaling (MCS) detection method. The width of the excitation pulses is easily controlled from the VPL allowing quick optimisation of the measurement conditions. External trigger capability The VPL lasers are compact, maintenance free, and user-friendly. Although they are designed to match Edinburgh Instruments spectrometers, they can be incorporated into any experiment thanks to their external trigger capability. Spectrally purified output Adjust pulse width and repetition rate with input trigger pulse Operation in CW mode Compact plug-and-play design Extremely low RF radiation Optimised collimated beam
