Beam Homogenized Stub Laser

The wavelength stabilized stub laser features high output power with narrow spectral bandwidth with a shaped and vertical beam profile that evenly spreads out the power density in a horizontal direction.

Designed to replace expensive DFB, DBR, fiber, and external cavity lasers, the multimode Spectrum Stabilized Laser offers superior  wavelength stability over time, temperature (0.007 nm/ºC), and vibration, and is manufactured to meet the most demanding wavelength requirements.  

λ (nm): 830
Min. Power (mW): 350
