SECTION 2: INSTALLATION
Proper installation of the injection seeder consists of making modifications to the host laser and
then installing the seeder.
2.1 HOST LASER MODIFICATIONS
Proper preparation of the host laser is essential for good seeder operation. Prior to making the
necessary host laser modifications, the host laser must be operating properly.
An overview of the modifications necessary for injection seeding are shown below in Figure 2-1.
Modifications include adding and/or modifying the Marx bank, stabilizing the Nd:YAG cooling
water temperature, attaching the piezo element to the high reflecting end mirror, adding additional
quarterwave waveplates, providing superior vibration isolation, and modifying the polarizer
assembly. These modifications are discussed in the following sections.
