OEwaves Announces Lock Box for locking two lasers

PASADENA, Calif. – January 18, 2023 – OEwaves, Inc., a leader in innovative photonic and electro-optics products and solutions, today announced a new product for phase locking of two lasers, the Hi-Q Laser Phase Lock System. OE5000 allows offset locking of two individual lasers separated in frequency by as much as 50 GHz.

Many applications such as coherent communications, metrology, gas sensing and quantum technology require locking a laser to a second “reference” laser to achieve high spectral purity or frequency stability. In many of these applications, the frequency of the laser to be locked and the reference laser can be as much as 50 GHz apart. OEwaves’ OE5000 allows achieving the lock in a simple setup with a fiber input carrying light from each laser and an electric output to actuate the lock. The programmable frequency interval is controlled by USB input from the user’s computer.

The OE5000 lock box can be used with any two pairs of lasers in 1300-1600 nm wavelength range with a voltage input to control and lock the frequency to the reference laser. In particular, it can be readily used with OEwaves Ultra-narrow linewidth lasers. Options for locking lasers at other wavelengths are also available.
