Pulsed LiDAR Optical Laser Source R01

Pulsed LiDAR Optical Laser Source

Product Introduction
Pulsed LiDAR Optical Laser Source product are 1550nm eye safety pulsed LiDAR source. Theconfiguration uses MOPA design, it can achieve high peak power, ns level pulse width and highrepetition rate. The module uses compact package with smart size, wide operating temperature range
and low power consumption. It is the ideal source for LiDAR, mapping, and range-detecting.

Control modes are:● P: Output power control mode: y is the output power
set point in mW. When y is not supplied, this command
displays the last APC mode setpoint.
● M: Manual pump control: y is not supplied. In thismode, each pump is driven at a fixed current specified
by the PUMP ISP command (ACC).
● D: Disable mode: y is not supplied. All pumps areshutoff.
