Range Finding Lasers

Range Finding Lasers Overview

Range Finding

Laser range finding is a term used to describe the process of determining the distance to a fixed object.  This process is essentially a simplified version of laser radar, and therefore has many of the same requirements as lidar lasers.  Since we are only considering stationary targets and distance is the only thing being measured, range finding lasers are always pulsed to measure the roundtrip time-of-flight and calculate the distance to the target.  An additional constraint on laser range finding is that not all lidar systems have is the need to be very careful about eye safety since they are typically operating over shorter distances and in more populated areas.  As a result, most of these lasers operate around 1.5 microns in wavelength, which is considered to be eye-safe because of the extremely high-water absorption.   On this page, you will see a list of all of the range-finding lasers including both passively and actively q-switched Er: Glass lasers.

GBS Series

GBS Series by BKtel

The GBS Series of fiber laser modules are a Broad Band Source generating a non-coherent and broad ASE spectrum that combines the C and L-Band of the erbium with up to 22dBm of output power. ASE Broadband Sources are also available in the 1 µm band of the Ytterbium and the 2 µm band of the Thulium. All our Broad Band Sources are proposed in module format or in a Bench Top configuration.

LGK Series

LGK Laser Series by Lasos

The LGK Series of Gas Lasers include a wide range of HeNe and Argon lasers with wavelengths at 488nm, 515nm, 543nm, 594nm, and 633nm.

OT Series

OT Series by Optitask

The OT series of Erbium Glass lasers are ultra-compact, high energy q-switched, solid-state lasers that are well suited for rugged, field applications such as active night vision and rangefinding. These air-cooled lasers are available in both lamp-pumped and diode-pumped configurations, with passive and active Q-switching options. With over 10,000 units in the field, the OT series is a proven technology operating in some of the more challenging laser environments.

QCL Series

QCL Series by MirSense

The QCL series is a high power pulsed Quantum Cascade Laser based on proprietary technology which incorporates high-powered diodes (typically watt-level) emitting in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm). The ITAR free MirSense technology exhibits outstanding performance in terms of power and wall-plug efficiency. This high-performance QCL assembly takes full advantage of MirSense’s state of the art technologies.

Wedge Series

Wedge Laser Series by Bright Solutions

The Wedge series of DPSS Lasers have been designed for OEM applications like micro machining of hard and soft materials, specialty marking, glass and crystals engraving, LIDAR, LIBS, Spectroscopy and medical diagnostics. High peak powers, with relatively low energy and heat generation, allows efficient ablation and non-linear interaction with most materials. The compact and lightweight package represents a great benefit in LIDAR and other aerospace applications, while short pulses give extremely precise time-of-flight measurements.
Second Harmonic (532 nm output) and wavelength conversion option widen the product application range.
