Industrial VCSEL Solutions (TO Packages)

Single-mode VCSELs in a hermetically sealed TO housing allow easy handling of the laser diode and are suitable for operation in demanding ambient conditions. An additional Z diode protects the laser diode from damage due to electrostatic discharge (ESD). The VCSELs also undergo a burn-in to stabilize the lasers. Various wavelengths are available, from 760 nm to 940 nm. TRUMPF also offers packages in which the TO housings are further integrated and, for example, are installed directly in printed circuit boards with the corresponding electronics in a highly automated manner. This allows customer-specific requirements to be fulfilled.

Polarization-controlled single-mode VCSEL

The single-mode VCSEL platform is designed for extremely low power consumption and high output power. The polarization lock achieves polarization control without compromising power efficiency.

Hermetically sealed VCSEL package

The TO package around the VCSEL hermetically seals the electronics inside the housing. No damage occurs even in demanding ambient conditions.

Temperature-controlled by TEC and thermistor

The TO housing with integrated TEC is for applications that require a large temperature window or spectral stabilization of the laser diode. This allows the laser temperature to be precisely controlled.

Available in various wavelengths

Product variants with wavelengths from 760 nm to 940 nm are available to suit the application requirements.

Everything from a single source

VCSELs in TO housings can be integrated into more complex systems in a highly automated manner. TRUMPF offers everything from individual components and TO packages to fully integrated modules.

Packaging: Integration of VCSEL

Highly automated systems take over the assembly and integration of VCSEL laser diodes in more complex systems. This also enables customer-specific adaptations such as the integration of driver electronics or special optics. The VCSELs can thus be handled safely and integrated easily.

Reliable oxygen spectroscopy with VCSEL

VCSELs in the 760 nm – 766 nm spectral range enable highly precise measurement of the oxygen concentration. With the help of the integrated thermoelectric cooler and by varying the operating current, the laser emission can be precisely matched to the desired spectral line.

Industrial encoder for the most precise positioning

Single-mode VCSELs are perfectly suited to use in optical encoders as they have a Gaussian-shaped beam profile and long coherence length. In addition, the hermetically sealed TO housing is perfectly suited for use in industrial environments.

Industrial speed and distance sensors

TO housings are robust enough for use in industrial environments. They are used as speed and distance sensors for various materials, including sensitive materials like fabrics.

Oxygen sensors (TDLAS)

Single-mode VCSELs in TO housing with TEC are excellent for TDLAS applications (Tunable Diode Laser Absorption Spectroscopy).

FTIR (Fourier-transform infrared spectroscopy)

Due to the low temperature dependence of the emission wavelengths (0.06 nm/K) and the narrowband spectral emissions of typically 100 MHz, temperature-stabilized single-mode VCSELs are particularly suitable as a wavelength reference for FTIR spectrometers.

Product variants on request with the following characteristics:

Temperature control

TO housings are available with and without temperature control (TO housing with TEC and thermistor).

Various wavelengths

Various wavelength configurations are available in the range between 760 nm and 940 nm.

Polarization-stable, integrated photodiodes

Polarization-stable single-mode VCSELs with monolithically integrated photodiodes are available.

Integrated VCSEL Modules

In addition to TO packages, more in-depth product integration can take place. Customer-specific adaptations such as the integration of driver electronics or special optics are possible. Highly automated systems integrate the VCSEL laser diodes in more complex systems.
