How to name rock type mining explosives?

The naming rules for rock-type explosives are as follows:
The name of the rock-type explosive is composed of five parts, and its general form is: (1) (2) (3) - (4) (5). For example: SYG—3K
(1) Representing the drug type, using a larger or a capital letter followed by a lowercase Chinese pinyin: S-water gel explosive; J-slurry explosive; A-ammonium ladder explosive; Ah-ammonium black explosive; Al-ammonium wax explosive.
(2) Indicates applicability, expressed in a capitalized Chinese phonetic alphabet: Y-rock type.
(3) Demonstrate the power of explosives, expressed in a capitalized Chinese phonetic alphabet: G-high power; Z-zhong power; D-low power.
(4) Indicates that different grades are represented by Arabic numerals and are generally arranged in the order of identification or registration.
(5) indicating a certain characteristic of an individual variety, represented by a capitalized Chinese phonetic alphabet; K-resistant to water.

Red Laser

Red lasers include DPSS (diode-pumped solid-state) Laser and diode laser. This series laser include 3 series: high power and stability, low noise and Single Frequency Laser. Free space or fiber-coupled (SM fiber, MM fiber, homogenization fiber) output available. They are widely used in bioengineering, fluorescent substance, raman spectra and so on. Following wavelength are available for red laser:
