Gentec-EO: Quick guide on laser beam divergence measurement

872fe49555995883594ee653c5d7a8c0c19ba5f1

Lasers are in demand for their well-collimated, single-wavelength electromagnetic beams. The low-divergence, single-wavelength radiation and vast range of available laser power ranges make them one of the most valuable tools for material processing in industry and research.

Laser beam divergence is one important parameter to know for laser manufacturers and users alike who need to take control of their laser spot size. From laser welding applications to wafer dicing or eye surgery, knowing your beam divergence is a must for building a functional setup and to direct the energy precisely where it is needed for a given process.

Here we present important concepts about laser beam divergencemeasurement. Understanding them will help you avoid wasting your energy where it is not needed!

Toptica: Multi-Laser Engine for Microscopy

iChrome CLE

The Toptica multi-laser engine iChrome CLE for biophotonics provides 405, 488, 561 and 640 nm with 20 mW at the end of the fiber. The cost-effective system is ideal for multi-color microscopy applications due to its compact design and economic operation. Even the 561 nm light is generated by a laser diode instead of a solid-state laser, allowing this system to be directly modulated at high speed (1 MHz) while maintaining complete-off, i.e. zero photons, in the dark state. The iChrome CLE is the latest member of TOPTICA’s iChrome product line which also includes the powerful iChrome MLE (up to 100 mW and four laser lines). All iChrome systems have a unified user interface, unique modulation features and COOLAC, TOPTICA’s proprietary and fully automated beam alignment algorithm guaranteeing consistent power out of the fiber.

Thorlabs: Temperature-Controlled Mini-Series Breadboard

Mini Temperature Controlled Breadboards

  • Compact Size: 5.00" x 4.00" x 2.46" (127.0 mm x 101.6 mm x 62.5 mm)
  • Double-Density 1/4"-20 (M6) and 8-32 (M4) Tapped Hole Pattern
  • Integrated TEC Element, Thermistor, Centrifugal Fan, and Heat Sink
  • Temperature Setting Range: 15 - 45 °C (Using Front Panel) or 5 - 45 °C (Using Software GUI)
  • Can be Used with  External Temperature Probe
  • Region-Specific Power Cord Included

The Thorlabs PTC1(/M) Temperature-Controlled Breadboard uses thermoelectric elements and active-air cooling to maintain a temperature selected by the user. The unit includes a TEC, controller, thermistor, centrifugal fan, and heat sink for thermal management within a compact 5.00" x 4.00" x 2.46" housing. The internal TEC element features bi-polar operation, meaning it can be used to heat or cool components on the surface. It can handle a maximum heat load of 18 W when the breadboard is set to the ambient temperature.
