  Fiber-Coupled Laser Diode Product - High Brightness
Apollo Instruments' fiber-coupled laser diodes offer the highest brightness and high power with unprecedented beam quality. These compact devices deliver up to 5kW through a fiber assembly with core diameter ranging from 0.05-1mm. These devices can be offered in various configurations. Fiber-coupled modules that deliver up to 60 watts are conductively cooled and ready for mounting on a heat sink. Devices with higher power are normally water cooled. Apollo's water- cooled devices are robust. There is no need to use de-ion water or ultra-filtration.
 
The fiber-coupled laser diodes provide ideal beam sources for system integration and offer the simplest and easiest way to deliver high-power laser light to a variety of applications. The devices are cost-effective pump sources for laser pumping (such as fiber laser pumping). They can also be excellent beam sources for material processing and medical applications. Due to the high brightness, the devices have been shown to be effective in direct laser applications such as metal cutting, marking, soldering, welding and silicon wafer treatment. Together with a focusing lens, some laser modules can easily achieve a beam spot with a power density over 4MW/cm2. Models are now available in a variety of wavelengths ranging from 780nm-1550nm. Although the standard modules are built with a single wavelength, multiple wavelengths can be combined. 

One of the unique characteristics of Apollo Instruments' fiber-coupled devices is that all the output is emitted from the fiber core. There is no cladding mode.

Options

In addition to our standard designs, Apollo Instruments offers many existing design modifications that allow for a high degree of product customization. Apollo Instruments also supplies a variety of optical options, such as low aberration focusing and/or collimation assemblies, mirrors, filters, spatial filters, and other accessories. Please inquire for further information if these options or other features can better help us meet your needs.
   
Pilot Beam
A low power visible diode laser can be integrated into the laser modules for tracking the laser output. Power to the pilot beam is integrated in Apollo's laser diode driver. If a different laser is used, a 2.5V-3.5V DC power source should be supplied.
 

 
 
  
 

Operation Modes
These laser diode devices can be designed to operate with high-power output in QCW mode and other pulse modes. The short pulse option allows the module to produce very short (ns level) pulses as a stand-alone device.
  

 
 
 

Photodiode Sensor
A photodiode sensor placed in the module provides the user with a precise gauge of the laser status.

 
 
 

TEC Cooling Stage
Some products can be equipped with our TEC cooling stage. Together with a thermal electric cooler (TEC) and heat sink, the cooling stage allows precision cooling. Based on your need, the heat sink can be air-cooled or water-cooled.

 
 
 


Laser Diode Driver
The advanced circuit design and layout of the laser diode driver provides a low noise, highly stable output current. External digital modulation input allows precision control of the laser output for use in a variety of applications. A slow-start sequence as well as multiple shorting and current limiting circuits provides superior protection during operation of the laser diode.
