The OE4045 from OEwaves is a Blue Laser that operates at a wavelength of 435 nm - 480 nm. It has a spectral linewidth from sub-Hz to 10 Hz and thermal tuning range of 10 GHz.This laser has an optional frequency modulation from DC to 1 MHz and integrated driver/controller. It has a residual amplitude modulation of -80 dB and thermal tuning range of 210 GHz. This laser can be controlled via USB or RS-232 interfaces and is available in a compact lab, rack-mount, or OEM package. It is ideal for quantum computing, coherent communication, atomic clocks, frequency control, optical metrology & spectroscopy, acoustic sensing,interferometric optical sensing, LiDAR, and Brillouin Optical Time-Domain Reflectometry (B-OTDR) temperature & strain measurement applications.
