The above graph shows the increase in efficiency in OPO conversion achieved with increased KTP element length. In the past, OPO efficiency
leveled off with 20 mm long elements, and actually dropped with longer elements. This was due to imperfections in the KTP elements.
Raicol’s crystal growth technology can provide long elements with few imperfections, which results in higher OPO efficiency.

Raicol produces KTP crystals with gray track resistance up to ten times greaterthan typical flux grown KTP. This is possible due to advances in the controlled
growth of KTP crystals, using proprietary modified fluxes and heat treatment.
These HGTR KTP elements are suitable for high power density applications,where many other KTP elements would suffer from gray tracks or photorefractive
breakdown.

Time (s)In the GRIIRA (Green Induced Infrared Absorption) test, an infrared laser beam passes through the KTP
element.
The initial measurement (at time 0) is the infrared absorption of the crystal. After a few seconds, a green
laser beam is allowed to go through the crystal as well. The green light causes an increase in the IR absorptionof the crystal. This effect has been show to correlate with gray tracking in KTP crystals.
The above graph shows that the Raicol HGTR KTP elements have both a lower initial IR absorption, andare affected less by the green laser. Thus, Raicol HGTR KTP is expected to have a higher gray track resistancethan regular flux grown crystals or hydrothermally grown crystals.

Periodically Poled KTP is an entirely new type of non-linear material. It can be
tailor- made for all non-linear applications within the transparency range of KTP,
without the phase matching limitations of bulk KTP. It’s effective non linear
coefficient is about three times larger than that of bulk KTP.
Raicol offers PPKTP in large production quantities, as well as small quantities
for development work.
KTP is a ferroelectric crystal. In the classic use of bulk KTP, it is important to havea single domain crystal. In PPKTP, a periodic domain structure is artificially inducedin the crystal. The exact spacing of these periods depends on the application,and ranges from a few microns to tens of microns. The period is induced in the
direction in the crystal that has the highest non-linear coefficient, as opposedto the bulk crystal, where the direction is dictated by the phase matching
constraints.
Some degree of crystal temperature control is necessary in using PPKTP.
PPKTP is produced in a multi-step process. An electrode of the desired structureis deposited on the surface of a KTP wafer, using micro lithographic techniques.
An electric field is applied to the crystal under carefully controlled conditions,thus inducing the desired change in domain structure. The resulting KTP is thentested, cut into appropriate pieces, polished and coated.
The technique lends itself to mass production at a reasonable cost.
PPKTP is available in standard elements for some common applications, suchas second harmonic generation of 1064 nm and 946 nm. It can be also be
specially designed and manufactured for specific applications.

RTP, which has only recently become commercially available, is the material of
choice for many NLO and electrooptic applications. It’s high optical damage
threshold makes it especially useful in high power SHG and OPO applications.
RTP’s high electrical resistivity is important for many electrooptic applications,and in the production of Periodically Poled RTP elements.

POENTAThe graphs above show the behavior of RTP and BBO Q switches at high repetition rates. In particular, the BBO shows Piezoelectricringing at 30 kHz, while the RTP Q switch shows no ringing at this frequency.
The BBO Q switch has a 2.5x2.5x25 mm element, while the RTP Q switch has two 6x6x7mm elements.

Some applications of OPO require compact size and vibrationless operation,
which may be achieved by using a monolithic design of the OPO element.
External (cavity) mirrors are eliminated in this design, and the mirrors are evaporated
onto the KTP crystal input and output faces directly. In addition, a higher frequency
conversion efficiency can be achieved (see a figure on next page).
Elements with flat mirrors are a standard product. A curved mirrors design isunder development and it is aimed to achieve a narrower divergence angle ofthe monolithic OPO element.

BBO (Beta Barium Borate) crystals combine very
wide transparency, moderately high nonlinear
coupling, high damage threshold and goodchemical and mechanical properties. BBO phasematches over a wide spectral range, yielding SHG
from 190-1780 nm.
