The Most Complete Line of Laser Drivers Can Be Found Here
Laser driver is used for driving laser diodes, and it can also be called laser diode driver or laser controller. We, at Analog Technologies, have been developing laser drivers for over 20 years and launched over 100 different types of laser drivers onto the market to date. The main advantages of our laser drivers are Their small size, low noise, high efficiency, and low cost.
Compared to other manufacuture's laser drivers, we excel in producing the lowest noise, such as the ATLS1A104D; the highest power density with the ATLS15A218D, which has the output current 15A and maximum output voltage 28V. It measures just 29*20*6 (mm), while the competition’s is 20* larger and harder to integrate into designs. We have DC input, AC input, high current, high speed and many other different types of laser drivers making us the industry leader with the most complete laser driver product line on the market today.
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 our diode laser drivers provide:
- Laser current setting and monitoring
- Control loop good indication
- Driving mode indication (for dual mode versions)
- 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 with each other. We have a full line of laser drivers/controllers:
- Low noise low current
- High efficiency medium current
- AC input high current high efficiency
- High current short pulsed

Frequently Asked Questions and Answers
High Voltage Constant Current Laser
Driver ATLS15A218 (New)
This laser driver, ATLS15A218, is an electronic module that has all the valuable and important, but often difficult to achieve simultaneously, features such as: 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 500kHz), wide modulation bandwidth, and small size. The wide output voltage range, 0.1VPS ~ 0.8VPS, allows driving one or multiple serial laser diodes at the same time, for up to 15A well controlled current at high efficiency. The extremely low noise between DC ~ 10Hz and low DC current drift make it ideal for driving diode pumped laser diodes.
High Voltage Constant Current Laser
This laser driver, ATLSxA217, is an electronic module that has all the valuable and important, but
often difficult to achieve simultaneously, features such as: 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.
Note: this series of laser drivers can be evaluated by the evaluation board ATLS216EV1.0.
High Voltage Constant Current Laser Driver ATLSxA212
In order to meet the need for driving high voltage diode lasers or driving a serial of diode lasers simultaneously, we have developed the ATLSxA212 series of 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 easily by using their compatible evaluation board, ATLS212EV1.0. These series of 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.
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 the evaluation board, or be used alone, as a dummy laser load, to emulate one or multiple laser diodes.
Constant Current CW Laser Driver ATLSxA202D
The ATLSxA202D series laser drivers have slightly different pin out as that of ATLSxA201D series laser drivers. This series of laser drivers have a synchronization function pin which allows using an external digital signal to synchronize the internal switching frequency of the PWM output stage. This function is useful when using the laser drivers with a switching power supply that has a similar switching frequency or has multiple such laser drivers on the same PCB, to eliminate the beating frequency interference. They are designed for driving laser diodes with low noise constant current and high efficiency. The "xA" in the part number specifies the maximum output current of the laser controller, it can be chosen to be: 500mA, 1A, 2A, 3A, 4A or 6A. The module is packaged in a metal enclosure, emitting zero EMIs, and has DIP mounting package. These laser drivers are of 100 % lead (Pb)-free and RoHS compliant.
Frequently Asked Questions and Answers.
1. Q: How to achieve highest digital modulation speed on a laser controller's output current?
A: For laser drivers ATLSxA201 and ATLSxA202, LIS pin should be toggled between these 2 voltages: a high value corresponding to the operation current and a low value corresponding to half of the threshold current of the laser the driver is driving.
For laser drivers: ATLSxA212, ATLSxA214, ATLSxA216, ATLSxA217 and ATLSxA218, set a high voltage value on the LISH pin corresponding to the laser operating current; set a low voltage value on the LISL pin corresponding to half of the threshold current of the laser the driver is driving. Then use a digital signal to drive the PCN pin.
