High-Energy Nd:Glass Laser

High-Energy Nd:Glass Laser

Recently, a 50J Nd:Glass laser produced by Beamtech Optronics Co., Ltd. was successfully installed and accepted.

Beamtech Optronics recently completed the installation and acceptance testing of a customized 50 J high-energy Nd laser system. The delivered system achieved stable nanosecond output, controlled spatial energy distribution and a 3 mm focused spot, meeting the customer’s requirements for high-peak-power scientific experiments.

This 50 J system was developed from Beamtech's MELAR high-energy Nd laser platform, which supports customized 20 J, 50 J, 80 J and 100 J configurations.

This laser can focus its beam to a 3 mm spot, generating a peak power density of approximately 80 GW/cm² at 1053 nm (>20 GW/cm² at 351 nm), making it ideal for applications that require high peak power density with a uniform focal spot energy distribution.

Melar Series Nd:Glass Lasers

Nd:Glass lasers use neodymium-doped (Nd) glass as the gain medium and are widely applied in fields that require low pulse repetition rates and high pulse energies (up to 100 J per pulse). Compared with other high-power solid-state lasers, Nd:Glass lasers offer the following advantages:

• High pulse energy: capable of delivering up to 100 J per pulse

• Excellent beam quality: uniform energy distribution allows precise focusing

• High laser conversion efficiency

• Relatively low cost

Why Nd Is Used for High-Energy Laser Systems

Nd uses neodymium-doped glass as the gain medium and is well suited to low-repetition-rate applications requiring extremely high single-pulse energy.

Compared with laser systems designed primarily for high repetition rates, a high-energy Nd laser can be engineered to provide:

• ◆  Pulse energies of tens to hundreds of joules

• ◆  Nanosecond pulse duration

• ◆  High peak power

• ◆  Large-aperture amplification

• ◆  Configurable spatial beam shaping

• ◆  Optional harmonic wavelength conversion

• ◆  Narrow-linewidth seed injection

These characteristics make Nd systems suitable for specialized scientific facilities where single-pulse energy and beam distribution are more important than a high pulse repetition rate.
