Note:

1. External mechanical dimensions can beredesignedto meet customer's exact requirements;

2. Laser rods customized to your exact requirements available upon request.Please tell us the diameter of the YAG rod when placing the order.

3. Detailed drawing and dimensions can be found from our websites.

5. If you want us to design a specific pump chamber, you need to tell us the specifications of YAG rod and lamps as follows:

1)    YAG rod: diameter and length;

2)    Lamp, dimension of arc length, outside diameter, overall length, end type (base diameter and length) etc or model number. Please refer to our websites for more details of lamps.

Ordering Information:

* When placing the order for the pump chamber, the buyer should tell us the dimensions of the rod and the lamp or lamp’s model so that we can give right O-rings.

* lamp connectors are not included in the pump chamber.

* The lamp and rod are not integrated into the pump chamber for convenient shipping. If integration is needed, the buyer takes its risk of the rod and lamp to be broken during the shipping. In general, separate package of lamp, rod and pump chamber are safer.

Remark: For a same pump chamber, larger rod will output much higher laser power but laser beam quality becomes worse.

How to Select a Pump Chamber

The most important parameter to select a pump chamber is the average power you want from the pump chamber. Once you finalise the power you want, then please remember the following points in mind:
