Actively Cooled
Leonardo fluid cooled laser diode arrays utilize a patented monolithic design that requires only filtered water (not deionized). This eliminates the most common failure mechanisms associated with microchannel cooled laser diodes. Requiring no o-rings or rubber gaskets, our laser diode arrays perform reliably in harsh environments.
Special features of the conductively cooled laser diode arrays:
- Wavelength range: 760 to 1.700 nm
- Filtered water, not deionized
- Scalable building block format
- Small bar-to-bar pitch for increased brightness
- Low pressure and water flow requirements
- Multi-wavelength in a single array
Fluid cooled laser diodes are available in two configurations:
CW-mode with laser power up to 2.5 kW or QCW up to 25 kW: Fluid cooled - T6 module
Scalable modules up to 1 MW laser power: Fluid cooled - Scalable module
VCSELs
The vertical-cavity surface-emitting laser, or VCSEL, is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer. Due to very good beam quality and low manufacturing costs VCSELs are used in various laser products, including fiber optic communications, laser printers, automotive & consumer electronic industries.
Special features of the Leonardo VCSEL’s:
- Wavelength range: 800 nm to 1.6 µm
- High brightness illumination (up to 12 kW/cm²)
- Fast modulation capability
- Low speckle
- Operation modes from ns pulses to CW
- Single and multiple emitter designs
Die VCSEL's are available in two configurations:
CW-mode with brightness up to 1 W/mm²: Edge Emitter Arrays
Pulsed-mode with brightness up to 100 W/mm²: VCSEL V1
LIDAR
Leonardo offers a line of illumination sources for camera systems and Advanced Driver Assist Systems (ADAS). Leonardo's products offer integrated control electronics, laser diode source and beam shaping optics in a single module. Optimized for performance and cost, both products offer a range of configurable options including variable power, wavelength and application-defined beam shapes and are based on Leonardo's VCSEL or edge-emitting laser diodes.
Special features of the LIDAR Illumination Sources:
- Wavelength range: 760 to 1.700 nm
- Integrated system with electronics, laser source and beam shaping
- Short pulses,
- VCSEL or edge emitting laser diode sources
- Application defined power, wavelength
- Customizable beam shapes
Die LIDAR Illumination sources are available in two configurationens:
High Beam™ - 10 kW Peak power @ 20 ns pulse: High Beam™
Low Beam™ - 3 kW Peak power @ 5 ns pulse: Low Beam™
