PPLN Chips
HC Photonics provides the standard chips designed for the common laser applications. Contact HC Photonics for special customized patterns. We also provide the related accessories such as the temperature control unit, crystal mount and also the infrared sensing cards for beam detection.
Conversion Configuration
5 mol.% MgO doped PPLN for Second Harmonic Generation (SHG) of blue to red light from a laser source between 950-2200nm infrared wavelength.
5 mol.% MgO doped PPLN for sum-frequency generation (SFG) of blue to red light from the conventional laser sources such as Yb/Er fiber laser, YAG laser or Ti:Sapphire lasers.
5 mol.% MgO doped PPLN for laser wavelength downconversion (e.g. optical parametric generation, difference frequency generation) of the conventional pump laser such as Yb fiber lasers, YAG laser, and Ti: Sapphire lasers.
PPLN (ridge) waveguide
The waveguide can be manufactured on a periodically poled crystal to form a frequency conversion waveguide. HCP provides two types of the waveguide to customers to satisfy the requirement of the different applications.
For the more technical introduction please see here.
Compared to the traditional ion or proton in-diffused waveguide, the ridge waveguide has a high damage threshold and wide-operation wavelength range due to the high refractive index difference of the core (LiNbO3) and the cladding. The good confinement leads to good conversion efficiency and feasibility of extremely low propagation losses.
Most of the waveguides are manufactured upon request, but some of them are available in stock for popular applications. See the typical specification below and just inquiry us with your specific wavelength.
Following table shows the typical specifications of the standard waveguide, for ordering:
1. Select the serial # covering your interested wavelength (e.g. 1064 nm SHG corresponding to WG-G)
2. Send an inquiry with specified wavelength to us and we will respond you the available waveguide length in stock.
3. For the wavelength not listed, please just send us the inquiry for detailed specifications.
The typical specifications of the waveguides
[regular grade (plus grade)]
*1 MFD (mode field diameter) tolerance +/-10%
*2 Normalized efficiency has a tolerance of +/-20% on the specified value (e.g. WG-G: 160-240%/W/cm^2)
