Single Frequency red laser at 640 nm with 1000 mW output power
21 Feb 2020
UniKLasers have recently launched second-generation Solo 640 Series of lasers, which deliver impressive output power of 1000 mW.
The new series now include customer-focused specification enhancements: advanced remote-control operation, extended power and wavelength stability, enabling more than 8 hours of non-stop operation along with the excellent specification parameters:
• TEM00 beam quality
• True single frequency
• Narrow linewidth
• Long-term wavelength stability <1pm
• High output power; various power levels available
• Long-term power stability <1%
• Integrated water cooling with an ultra-low noise chiller
• Small footprint
High resolution holography, interferometry and Brillouin scattering results depend on the single frequency nature and specifications of the laser being used. UniKLasers Ltd, UK has developed a technology to produce highly stable ultra-narrow linewidth laser output in a wide range of wavelengths at high power. Read more.
The creation of holographic images depends on the power, stability and linewidth of a laser to give clear resolution with a deep field of view. The same is true for interferometry and Brillouin scattering, which has the added requirement for an output without side-bands to the main laser frequency peak.
UniKLasers Ltd, Edinburgh, UK, designs and manufactures single frequency lasers in a wide range of wavelengths using a technique called Bragg Range Michelson Mode Selection (BRaMMS). The technique replaces an end cavity mirror with a volume Bragg grating and Michelson interferometer to create the mode selectivity of a single mode laser. The result is an ultra-stable laser output that is mode-hop and drift free and has a high spectral purity with linewidths < 0.5 MHz and
With the wavelength now being a function of cavity length, the stability of the output is reliant on reducing fluctuations in the position of the end mirrors. This is easily compensated for by using PZT control linked to a feedback mechanism that corrects any expansion/contraction of the laser head. This feedback loop has the added benefit in that it allows for a fine tunability of the wavelength output, or alternatively locking the absolute frequency to an external reference.
The lasers are therefore ideal for such applications as
