Lepton IV OEM Series
Diffraction Limited Diode Lasers

Lepton IV OEM lasers


  • 375nm to 1550nm
  • Circular Gaussian beams
  • Low wavefront error
  • Temperature controlled
  • High stability
  • Customized for your application


The Lepton IV Series of temperature controlled lasers are designed to give diffraction limited output with narrow linewidth and very high stability. They are a very affordable alternative to gas or solid state lasers. A nice benefit is they operate at low voltages, are very compact and last a long time.

Output power can be adjusted from zero to full output using the potentiometer or an external voltage. Temperature can also be adjust slightly to tune the wavelength a little with the potentiometer or external voltage. Monitoring pins can monitor the laser current, photodiode current, set temperature and actual temperature. An enable pin can be used to turn on/off the laser and temperature controller but still leave the main power on. Laser housing has ample mounting holes

These lasers can be customized to your requirements. Examples are beam combining, different beam shapes, focused spots at a distance, integration of optical elements, or wavelengths not listed.

Accessories include beam expanders, focusing optics, filters, waveplates, polarizers, etc.

* These lasers can operate with a single longitudinal mode with high wavelength stability.

Many more wavelengthsa and output powers are available for OEM users. These lasers can be customized for your application. Optical assemblies, detectors or other optoelectronic or mechanical devices can be integrated with your laser for a complete optical engine.

Many of these lasers operate in a single longitudinal mode. Please call or email for more info.

Specialty Lasers

We have specialty diode lasers that are used in certain applications. Lasers for Raman are used in medium to low resolution Raman applications. Grating Stabilized Lasers are used in Raman or interferometry. Focused Spot Lasers can be used in particle analysi, cytometry or remote sensing.


Accessories include Beam Expander, focusing elements, optical isolators and other optics that can be integrated into the laser head.
