DBR Diode Lasers, Single ModeSingle Mode
Description:DBR Lasers, 760nm .. 1083nm, single mode, narrow linewidth with good side mode suppression. Single mode emission is ensured via a Bragg grating. Check our stock list for availability.
Distributed Bragg Reflector (DBR):
Distributed Bragg Reflector (DBR) Diode Lasers are tunable single mode diode lasers. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material. The optical gain is provided by double heterostructure which include several Quantum Wells for electronic confinement. Typcal emitter width range between 3µm and 7µm. The single mode emission is enforced by a Bragg grating with the laser chip. The surfaces of the laser chip act as cavity mirrors due to the difference of the refractive index of the laser material and the surrounding air. The rear facet of the laser chip is provided with a high reflection coating. The emission wavelength of the DBR laser is tuned by a synchronized changing the current of the Bragg and the Phase segment of the laser. Distributed Bragg Reflector (DBR) Diode Lasers are available with up to 100mW at 1063nm and 80mW at 1083nm. These diode lasers are longitudinally and spatially single mode. They can be tuned up to 100GHz mode-hop free. Please check our data sheets.
DBR Lasers are available in 9mm TO-cans, TO3 cans with an integrated thermoelectric cooler or butterfly packages with thermoelectric cooler and single mode fiber coupling. Please note that the output power is reduced to typically 20% of the nominal power for the fiber coupled butterfly versions.
