QPM devices enable arbitrary wavelength conversion that is not possible with birefringent wavelength conversion devices (BPM) by designing the poling period. The converted light can achieve a circular Gaussian beam without walk-off. With over 20 years of design expertise, we provide wavelength-conversion QPM devices tailored to your requirements.
PP-Mg:SLT has high material durability and can easily generate 5-10 W class 532 nm CW light in a single pass from a 1064 nm laser. It frees you from absorption related issues such as GRIIRA (thermal lensing) and gray track, which posed difficulties at around 3 W with PPLN and PPKTP.
Enables two wavelength conversions with a single device. Normally, in third-harmonic generation, two elements are required: an SHG element and an SFG element that generates THG. With QPM, these are integrated into a single element through pattern design. It is optimal for downsizing, as components such as focusing optical systems and temperature control systems can be reduced by half.
To meet your request for simple and highly efficient wavelength conversion with your laser, the Fan-out PP-Mg:SLT enables immediate generation of converted light across the 340-5500 nm range, tailored to your existing laser. Owing to the fan-out structure, phase matching can be achieved simply by shifting the position, eliminating the need for temperature control for basic verification. All types are always in stock. AR coating can also be provided upon request.
In femtosecond lasers, optical combs, broadband light sources, and similar systems, the wavelength bandwidth of the incident laser light may not be uniquely or stably determined. Furthermore, when performing wavelength conversion of such light, it can be difficult to determine the appropriate parameters, such as whether to prioritize efficiency in terms of power or to maintain pulse width and bandwidth. For such applications, a QPM device design that can easily identify an optimal solution is the bandwidth selectable device. By varying the interaction length for wavelength conversion or continuously changing the chirping, it becomes possible to arbitrarily select the wavelength bandwidth of both the incident and converted light.
PP-Mg:SLT waveguides are waveguide-type wavelength conversion devices constructed by drawing a cladding layer on PP-Mg:SLT using an fs laser. This device was created in response to the need to leverage the power tolerance of PP-Mg:SLT material while achieving higher conversion efficiency. Compared to bulk devices, the conversion efficiency is more than an order of magnitude higher. Although conventional waveguide devices have limitations on input power, this waveguide can accept laser input in the several-watt class, and can generate more than 3 W of visible output as a conversion component. Despite its waveguide structure, it maintains the bulk-level laser durability inherent to the material.
