1064 nm Laser Diodes

What Is a 1064 nm Laser Diode?

A 1064 nm laser diode is a semiconductor source of coherent light that operates in the near-infrared (NIR). This wavelength is well known in industry, research and medical applications due several advantages such as deep surface penetration, low scattering, efficient absorption in certain materials. and stable performance under adverse operating conditions.

Types of Light Sources in 1064 nm Laser Diodes

1064 nm diode lasers are available in various configurations adapted for specific equipment and applications f.e. spectroscopic instruments, fiber-coupled laser modules, and pumping systems for solid-state lasers.

Fabry-Perot (FP) Laser Diodes

One of the most common 1064 nm laser diodes are FP diodes. The basis of their design is a simple resonator — a cavity with two highly reflective mirrors that amplifies emission at a specific wavelength.

Applications:

• Pumping sources for fiber lasers;
• Optical sensors;
• Metrological instruments;
• Medicine;
• Industrial material processing.

Distributed Feedback (DFB) Laser Diodes

1064 nm DFB laser diodes have a built-in periodic grating in the active region to provide single-mode operation. This makes the devices an ideal choice for high-precision applications.

Applications:

• Optical communications with dense spectral multiplexing;
• High-resolution spectroscopy;
• Optical coherence tomography;
• LiDAR sensors.

Pulsed Laser Diodes

These laser diodes create ultrashort light pulses with a high energy level. They provide high peak power and accuracy in maintaining the required wavelength.

Applications:

• Time-resolved spectroscopy;
• Optical telecommunications;
• Medical laser surgery;
• High-energy industrial material processing.

Key Specifications of 1064 nm Laser Diodes

1064 nm Laser diodes have following key features:

• Single-mode (SM), multimode (MM), constant-wave (CW) and pulsed-wave (PW) implementations for various applications.
• Wide optical power range up to 1 W for SM operations and up to 15 W for MM operations.
• Spectral line width —  less than 0.5/5 nm for SM/MM Fabry-Pérot laser diodes, respectively, up to 5 MHz for SM DFB lasers.
• Operating temperature range — up to 70°C.
• Formfactors — TO-Can, C-mount, fiber-coupled, butterfly package.
