Where to Buy External-cavity Diode Lasers

RPMC Lasers offers a wide selection of VBG based external-cavity diode lasers, available in wavelengths from ≈633 nm to ≈1070 nm, and from ≈10s of milliwatts up to ≈130 W output power. These lasers are available in both fiber-coupled and free-space, and as both OEM components and modules as well as turnkey systems. VBG based external-cavity diode lasers are used in many applications, including fiber and DPSS laser pumping, spectroscopy, Raman spectroscopy, CARS, differential absorption, and many more.

Gain Chips are modified Fabry–Perot laser diodes with an excellent AR coated output facet. While not self-lasing they are intended to be operated in External Cavity Diode Laser setups (ECDL), such as in Littman or Littrow configuration. With external feedback they reveal narrow single frequency operation in combination with superior tuning capabilities.

The Micron laser is a mode-hop free tunable external cavity laser for output powers of up to 300 mW. Versions with emission wavelengths between 638 nm and 1700 nm are available.

Alpes Lasers offers mid-IR external cavity lasers with wavelengths spanning 4.3 to 14 μm. External cavity kits with integrated laser control electronics are also available. These are Fabry-Perot lasers designed for maximum width of the gain profile.

TOPTICA offers ECDLs with unique tuning capabilities. The CTL lasers tune up to 110 nm without any mode hop. Finding resonances of quantum dots or micro resonators as well as spectroscopy has never been easier. TOPTICA continues to provide the DL pro, which is now available at even more wavelengths and is well suited for laser cooling and many other AMO experiments.
