Laser Diode Controllers/Drivers

Our laser drivers/controllers are designed for driving laser diodes with high stability, low noise, and/or high power efficiency. These are some of the functions diode laser drivers provide: laser current setting and monitoring, control loop good indication, driving mode indication (for dual mode versions), stand-by, and shut down. Due to their high efficiencies, most of our laser drivers/controllers can work without heat sinks. In addition, our laser drivers/controllers have complete metal shielding, which prevents the laser drivers/controllers and other electronics from interfering from each other. We have a full line of laser drivers/controllers: low noise low current, high efficiency midium current, AC input high current high efficiency, high current short pulsed, etc. The table below shows a list of our laser drivers/controllers.

High Voltage Constant Current  Laser Driver

In order to meet the need for driving high voltage diode lasers or driving a serial of diode lasers simultaneously, we have developed ATLSxA212 series laser drivers/controllers: ATLS500MA212, ATLS1A212, ATLS2A212, and ATLS3A212. Their input voltage can be between 4.5V to 15V, the output voltage can be from 1V to (VPS -1V), where VPS is the power supply input voltage. The maximum output voltage can reach 14V when powered by a 15V supply. They have 4 current capability versions, 500mA, 1A, 2A and 3A, and are packed in 2 styles: DIP (Dual In Line) through hole package and SMT (Surface Mount Technology) package. The former has the part number with a suffix "D", for the latter the suffix is "S". For example: ATLS2A212D or ATLS2A212S. The main features are: high efficiency, high output power, small size, high current stability, low output noise, and wide modulation bandwidth. These controllers can be evaluated conveniently by using their evaluation board, ATLS212EV1.0. Since these series laser drivers can output high power and the high power lasers are often costly. In order to avoid making costly mistakes when evaluating this series of laser controllers, we have also developed a load assembly that can be used to emulate the expensive laser diodes for evaluating the laser controllers.

High 

Voltage Constant Current  Laser Driver

This laser driver, ATLS4A217, is an electronic module that has all the valuable and important, but often difficult to achieve simultaneously, features simultaneously: wide input and output voltage range, high output current capability, high efficiency, low output noise (but it has an output 4mVp-p ripple voltage at 700kHz), wide modulation bandwidth, and small size. The wide output voltage range, 2.8V ~ 22V, allows driving one or multiple serial laser diodes at the same time, for up to 4A well controlled current at high efficiency. The extremely low noise between DC ~ 10kHz and low DC current drift make it ideal for driving diode pumped single mode laser diodes to achieve mode-hop-free and narrow optical wavelength drift, thus, long coherent length. Because of the high efficiency, the laser driver generates small amount of heat, thus, no heat sink is necessary for normal operation. The fully shielded case blocks all the incoming and outgoing EMIs (Electro- Magnet Interferences).

Laser Driver Load Assembly

Load assembly is designed to emulate laser diodes for evaluating laser drivers. These laser drivers can be used to drive one or multiple laser diodes with high efficiency and low noise for DPSSL, EDFA, or fiber laser applications. They accept wide range input voltage and their output voltage can be from 0V to almost the same as the input voltage. The size is very small, but can output high current, high voltage, thus high output power. In addition, these laser drivers have low output noise (except that there is a 500kHz 4mVp-p ripple voltage at the output) and wide modulation bandwidth. This laser load assembly can be used with this evaluation board, or be used alone, as a dummy laser load, to emulate one or multiple laser diodes.
