Oven & Temperature Controller

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

Precision Crystal Oven

	Model S
Host Crystal Size	up to 7mm x 7mm x 25mm
Standard Mount	standard 1Ў± mirror mount
Temperature Range	Room Temperature to 220Ўг C
Accuracy	0.1Ўг C
Weight	105g
Power Consumption	15W/110VAC or 15W/220VAC

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.

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

Applications:

uLBO NCPM SHG of Nd:YAG/YLF/YVO4 Lasers.
uLBO NCPM OPO Pumped by SHG of Nd:YAG/YLF/YVO4 or Ti:Sapphire lasers.
uKNbO3 NCPM SHG of 860-940 nm (a-cut);SHG 990-1070nm (b-cut).
uLiNbO3 NCPM SHG of YAG/YLF/YVO4
uIncrease damage threshold of KTP, LiNbO3 and BBO crystals
uStabilized high power SHG, THG, 4HG and 5HG ofNd:YVO4

Application Notes:

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	148Ўг C -170Ўг C 40Ўг C
KNbO₃(a-cut)	SHG 860-940nm	20Ўг C-180Ўг C
LiNbO₃	SHG 1064nm	120Ўг C
*KDP**	SHG 532nm	52.1Ўг C
ADP	SHG 532nm	51.2Ўг C
