結晶オーブン&温調器

Abal OptoTek社 (AOTK)



精密結晶オーブン&温度コントローラー

We provide specially design precision crystal oven and temperature controller to install, heat and stabilize crystal to a certain temperature. In response to the demand of precision crystal oven and temperature controller,and the trend of miniaturization of optical devices, AOTK now introduces our second generation of crystal oven and temperature controller.  

 

OTC-I OTC-II

                      

 

Precision Crystal Oven Specifications
OTC-I OTC-II
Host Crystal Size up to 7mm×7mm×25mm up to 6×6×35mm
Oven size Φ32mm x 38.1mm (1.5") Φ55mm x 60mm
Temperature Range Room Temperature to 220°C Room Temperature to 160°C
Accuracy 0.1°C  
Weight 105g   300g
Power Consumption  15W/110VAC or 15W/220VAC 20W/110VAC or 20W/220VAC
Connector 4-pin audio plug  
Cable 4 lines cable about 1 meter  

Option: Oven can be added windows on both end faces

The crystal oven has a small footprint which allows the oven to be mounted on standard 1" optical mounts. This is very important for quick experiments where limited space and time do not allow specially designed mechanical part to fit in. It also saves precious time and money for product development.


Temperature Controller Specifications


The temperature controller is microprocessor controlled, and has dual line 4 digits LED display (set point and real temperature). It is very easy to operate, and accepts both 110V and 220V power sources.

Temperature Range   Room Temperature to 220°C  
Warm-up Time   60 minutes  
Resolution   0.1°C  
Stability   better than ±0.1°C  
Dissipation Power   < 25W  
Power Consumption   < 5VA  
Environment Temperature   -10oC to +55oC  
Weight   300g   400g
Set point range   Selectable  

 Slow heating rate is suggested for LBO crystal, in order to prevent coating crack
    due to its inhomogeneous expansion.


Applications
 ● LBO NCPM SHG of Nd:YAG/YLF/YVO4 Lasers
 ● LBO NCPM OPO Pumped by SHG of Nd:YAG/YLF/YVO4 or Ti:Sapphire Lasers
 ● KNbO3 NCPM SHG of 860-940nm (a-cut); SHG 990-1070nm (b-cut)
 ● LiNbO3 NCPM SHG of YAG/YLF/YVO4
 ● Increase damage threshold of KTP, LiNbO3 and BBO crystals
 ● Stabilized high power SHG, THG, 4HG and 5HG of Nd:YVO4


Application Note

One of the major application of temperature controlling in nonlinear optical conversion is to use the Non-Critical Phase-Matching (NCPM) for some non-linear optical crystals, e.g. LBO and KNbO3. NCPM is preferred because it could generate superior beam quality and efficiency. It has very large acceptance angle and zero walk-off which are very important for doubling tightly focused laser beam or laser beams with large divergence.


NCPM Applications

 
Crystal   NLO Applications   Temperature
LBO   SHG (I) 1064nm,1053nm,1047nm
SHG (II) 1320nm  
148°C - 170°C
40
°C  
KNbO3 (a-cut) SHG 860-940nm   20°C - 180°C  
LiNbO3   SHG 1064nm 120°C  
KD*P   SHG 532nm 52.1°C  
ADP   SHG 532nm   51.2°C  

Installation of Crystals





                 

As the figure shown above, to install crystal in the crystal oven:


 
1 Turn the #2-56 screw on the side of the crystal oven clockwise to pull up the

    pressure bar inside the crystal oven, until there is enough room for the crystal.
2. Put the crystal into the oven by sliding it into the square hole of the crystal
    oven. Use wide blade plastic tweezers to hold the crystal and push it into the
    square hole. Avoid touching the surface of the crystal clear aperture at all time.
    Put the crystal in the center of the oven.
3. Turn the same #2-56 screw on the side of the crystal oven counter-clockwise to
    release the pressure bar inside the crystal oven, after the pressure bar touches
    the crystal top, release an extra two rounds – this will give enough force for the
    pressure bar to hold the crystal. 


Caution!
Do not try to adjust the fixed setscrew, which is glued to the crystal oven.
Do not release the pressure bar without the crystal inside the crystal oven, and
    do not continue to release the pressure bar when the #2-56 screw is already out
    of the threaded hole – try to screw the #2-56 screw back into the pressure bar for
    at least one round. Over-release the pressure bar will let the pressure bar fall off
    the crystal oven and it is very difficult to put it back on, without special tools.
