Special Crystal Mount for high power applications

--- clear annodized, flexible and no glue!

 In nonlinear optical conversion processes where high power laser sources are involved. It is essential to avoid the use of glue or double sticky tape. Also, the use of glue and sticky tape means that you can not easily take out the crystals for cleaning or repolishing. On the other hand, without glue or double sticky tape, the mounting of nonlinear optical crystals still has to be very secure and stable and, at the same time, protect the crystal from chipping or cracking.

The special crystal mount presented here addresses such concerns.  


Features

            The clear annodize is an essential design in laser devices that handles high laser power.

            This design is much superior to the setscrew design where the pressure of the set screw is very unpredictable and often result in crystal chipping and damage.

            The mount minimizes the crystal movement in the sensitive direction that the crystal will not move during cleaning with air duster or minor shock during transportation.

The BSHG-UV system's computer control function (optional) allows for automatic tuning and scanning without the need to change filters, optics, or crystals.

Designed for:

Modular Structures:

For flexibility, BSHG-UV is offered in modular structures:

Specifications

Tuning range: 3 BBO crystals double 410nm ~ 900nm, generate UV 205nm ~ 450nm. Short-UV(205nm to 225nm), Medium-UV(220nm to 290nm) and Long-UV (280nm to 450nm).

Doubling Efficiency: Depends on the beam quality and intensity of the input beam. Tight focusing with lens is not recommended by CASIX to increase intensity. Please check CASIX's C-Doubler for doubling weak (<50MW/cm2), and highly diverging(>1.5mrad) beams.

Input Polarization: Vertical (default) or Horizontal (polarization rotation prism pair required)

Output Polarization: Horizontal, 100:1 (For >105:1, use CASIX a-BBO UV polarizer).

Input Beam diameter: 6mm or less (nominal), larger aperture is possible as an option.

All specifications are subject to change without notice.

Dimensions: (all dimensions are in inches, unless otherwise specified)

BMIX-UV

The BMIX-UV system uses two BBO crystals. First, it doubles the input from an OPO/Dye laser to generate UV from 230nm to 270nm, and then mix the UV with the 1064nm from a Nd:YAG laser to generate UV from 189nm to 227nm. The BMIX-UV is the best choice for narrow bandwidth OPOs from Spectra-Physics and Continuum, where the directly doubled UV only covers >220nm.

Doubling Efficiency: Depends on the beam quality and intensity of the input beam.

Input Polarization: Default: Visible, Horizontal; 1064nm, Vertical; UV, Vertical Polarization other than Default will need polarization rotation prism + dichroic mirror.

Input Beam diameter: 6mm or less (nominal), larger aperture is possible as an option.
