  Collimated Laser Diode Product - Free Space
Apollo Instruments' collimated laser diodes offer high power with superior beam quality. These compact devices deliver output beam power ranging from a few watts to 3kW having single wavelength with divergence angles as low as 3mrad. The low-powered devices are conductively cooled and ready for mounting on a heat sink. The high power devices are normally water-cooled.

Apollo's water cooled devices are robust. There is no need to use de-ion water or ultra-filtration. The collimated laser beam can easily be focused or combined with conventional optics to provide the exact spot size or geometry needed. Apollo's collimated laser diodes provide ideal beam
 
sources for system integration and offer the simplest, easiest way to deliver high-power laser light to a variety of applications.

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.
 
   
Pinhole Spatial Filter
Stray light can be removed from collimated laser modules without changing the polarization, which results in a cleaner focal spot.
 
   
 

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 very precise gauge of the output power.

   
 

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.
