Narrow Linewidth Laser Diode

The coupling reduces the laser diode s natural linewidth by a factor of more than 10 000 resulting in an instantaneous linewidth of less than 200 hz.

Narrow linewidth laser diode.

Careful thermomechanical control and high precision alignment inside the laser is important to achieve high stability in the output wavelength and linewidth especially when operating the laser at varying ambient temperatures. The extremely narrow linewidth broad temperature operating characteristics and low power consumption deliver affordable portable instrument quality performance for a broad range of instrumentation applications. Here at rpmc lasers we offer a wide range of diode and diode pumped solid state dps narrow linewidth lasers. Ondax s 685nm wavelength stabilized laser diode is a single mode single frequency laser packaged in an ultra compact to can footprint.

Lasers in this series are the ideal laser choice for every demanding raman spectroscopy application. Narrow spectral linewidth diode lasers laserglow offers a wide array of narrow spectral linewidth 0 03nm nm diode lasers. The devices are offered at wavelengths of 532 638 785 808 830 976 and 1064 nm with an output power up to 800 mw. Narrow linewidth lasers overview.

The spectral linewidth is very narrow typically less than 0 1 nm due to an integrated volume bragg grating vbg and. Proprietary volume bragg grating design enables ultra narrow laser linewidth. 370 nm 532 nm ingan gan. Search every laser λ power package.

The laser diode and resonator are both mounted to a thermoelectric cooler for wavelength stability also allowing the laser to be thermally tuned over a 2 nm range. Now a russian research team has demonstrated a method for turning the output of a compact cheap laser diode into a powerful narrow linewidth laser source capable of driving on chip frequency combs and other applications nat. To achieve that bit of legerdemain the team cleverly used optical feedback. While all lasers are inherently monochromatic unless care is taken to stabilize the spectral output the center frequency can vary over time casing the time averaged spectral linewidth to broaden.
