Bright Solutions develops and manufactures state-of-the-art ns, sub-ns, diode-pumped solid-state (DPSS) lasers and high-brightness diode laser modules for the military, aerospace, medical and science sectors.
The firm’s DPSS standard portfolio includes efficient, compact and reliable sources at 1,064nm, 532nm, 355nm, 266nm, 15XXnm and 3um.
Diode laser modules are also available in several wavelengths, providing high-power continuous wave (CW) and pulsed emission, with fibre-coupled or free space collimated output.
Bright Solutions develops DPSS and dedicated diode laser solutions tailored to customer needs. These products are made using the firm’s experienced laser design and custom-orientated engineering.
CW and QCW diode laser modules for ranging
The firm’s BDL and BFP series is based either on diode arrays or single-emitter technology. The ranges are particularly suited for direct applications, ensuring long-lifetime and easy integration.
According to package and driving operation mode, it is possible to provide a CW output power of up to 400W and a peak power up to 2kW.
The most common wavelengths the firm provides are 8xx, 9xx, 1,064nm, while 1,470nm and 1,550nm modules are available on request.
All of diode modules can be configured both as fibre-coupled modules (SubMiniature version A or fibre connector) and for free-space propagation with collimated or custom-shaped output.
Integrated diode laser modules for illumination and designation
Diode laser modules can be integrated in a rugged and miniaturised package with current drivers, temperature controllers and interface electronics, in order to offer a solution completely sealed and qualified for airborne applications.
Power supply voltage, communication protocols and connectors are designed and tested according to the relevant MIL or custom specifications.
Sub-ns MOPA DPSS lasers for high-resolution mapping LIDAR
The Wedge DPSS laser family consists of very stable sub-ns (300ps-600ps) laser models both for high-energy and wide repetition rate range (10kHz-200kHz), making these laser sources ideal for high-resolution mapping LIDAR systems.
Master oscillator power amplifier laser system (MOPA) configurations are also available in order to offer higher energy and/or repetition rates.
Several laser sources were designed, manufactured and integrated in whole systems, consisting in DPSS laser source, scanner, photo detectors and a complex hardware and software equipment, actually working both in civil and military airborne applications.
High-peak power DPSS laser source for ranging and atmospheric LIDAR
Wedge HB and XB laser models can provide very high-peak power laser pulses, for example up to 4MW at 1,064nm with 1ns pulsewidth. They are available at 1,064nm, 532nm, 355nm, 266nm and also at 1.5um.
One of the main applications of such laser sources is atmospheric LIDAR, because of their high-pulse energy and short pulsewidth.
The 1.5um version provides up to 1mJ pulse energy at 1kHz and can be used for eye-safe operation because of the intrinsically safe emission wavelength.
As an example, the firm realised a three wavelength laser 4mJ – 1ns – 1kHz at 355nm, 532nm and 1,064nm integrated in whole LIDAR systems designed for atmospheric and pollution measurement.
High-power nanosecond DPSS lasers for bathimetric LIDAR
The amplified lasers for bathimetric LIDAR are based on stable and compact ns oscillators. They are available both at 1,064nm and at 532nm with 6mJ pulse energy at 10kHz and a 600ps to 2ns pulse duration with an electrical efficiency higher than 20%.
The beam shape and the pointing stability are specifically tested over hundreds of hours, in order to guarantee a reliable laser source to integrate in complex time-of-flight measurement systems.
These laser sources are ideal for bathimetry, where the near-infrared (NIR) emission is used for the mapping of the coastal zone, and the green radiation allows for mapping of the underwater.
