Bathymetry Lasers

What are Bathymetry Lasers?

Laser bathymetry takes advantage of the absorption properties of water to map the depths of large bodies of water including lakes and oceans from a passing airplane. This is achieved by shooting two different pulsed lasers whose pulses are synchronized, to the water below and using time-of-flight (TOF) laser radar to determine the total round-trip distance.   In this case, one laser is chosen in the near-infrared, where water is highly absorbent, and the other is in the visible spectrum where water is highly transparent.  The difference in TOF between the two bathymetry lasers will provide the depth of the body of water. Traditionally, 1064 nm and 532 nm are the two wavelengths used for this application, but it is important to note that most combinations of near-infrared and visible lasers will work.  On this page, you will find a list of all of the bathymetry lasers we offer.

Microchip Series

Bright Microlaser Microchip SB1 Laser

The Microchip series is a line of ultra-compact, passively q-switched, single longitudinal mode (SLM), narrow linewidth, DPSS lasers that offer exceptional performance in a compact form factor. The lasers feature pulse durations ranging from 400 ps to 2 ns, energy levels up to 80 µJ, and repetition rates up to 100 kHz. Available in wavelengths from the UV to the NIR, this series is designed for OEM integrators and researchers working with LIDAR, 3D scanning, LIBS, night vision, and more. The lasers offer both nanosecond and picosecond options and are interchangeable with the same form factor and electrical and software interfaces across wavelengths, making them a flexible and versatile solution. 

Wedge Series

Wedge-XF-1064: 1064nm Picosecond Laser

The Wedge series is a line of DPSS lasers designed specifically for OEM applications such as micro machining of hard and soft materials, specialty marking, glass and crystal engraving, LIDAR, LIBS, spectroscopy, and medical diagnostics. These diodepumped lasers, based on proprietary fast Q-switching technology, are compact, sealed, and monolithic which makes them insensitive to vibrations and harsh environments. With high peak powers and relatively low energy and heat generation, they allow efficient ablation and non-linear interaction with most materials. The compact and lightweight package is a great benefit in LIDAR and other aerospace applications, while short pulses provide extremely precise time-of-flight measurements.
