Diode laser stack family
800 W diode laser stacks
The public 800 W page documents three SKUs. Each is 800 W and 16 bars × 50 W. They are not one mechanical or electrical part. Drive current, voltage, duty cycle and cooling water are published only for HMA-808-50-16-D1.
A 2-year warranty is stated on the source page for Y084 and Q4716. That sentence is recorded below as a catalog note. This site does not turn it into an offer, and it does not extend it to A2377, which has no warranty sentence in its SKU record. Prices on the source page are not repeated.
Source checked 7 November 2026: public catalog page. Chip names describe bars in that catalog. They are not a claim that Hangzhou SG manufactures those chips.
| Published name | Item code | Wavelength / bars | Stack | Chip description in the catalog | Other published note | Catalog location |
|---|---|---|---|---|---|---|
| LST-1016AI | Y084 | 808 nm | 16 bars × 50 W | Chinese chip bars | Height 37 mm. The source page states a 2-year warranty for this SKU. | SKU record |
| LSR-1016AI / DVS-1016AI | Q4716 | 808 nm | 16 bars × 50 W | US Coherent chip bars | Height 37 mm. The source says LSR is the former series name, now called DVS. The source page states a 2-year warranty for this SKU. | SKU record |
| HMA-808-50-16-D1 | A2377 | 805–815 nm | 16 bars × 50 W | Chinese chip bars, catalog classification | Bar pitch 2.18 mm. Emitting area 10 × 32.7 mm. Drawing dimensions 40 × 39 × 49 mm. AuSn solder. Macro-channel water cooling. The source states no compatibility with the LST, LSR or DVS models. | SKU record |
Drive and cooling published only for HMA-808-50-16-D1

- Current
- 45 A typical, 50 A maximum
- Voltage
- 28.8 V typical, 32 V maximum
- Duty cycle
- 20% typical, 30% maximum
- Pulse width
- 20 ms typical, 200 ms maximum
- Frequency
- 1–10 Hz
- Coupled limit
- The maximum limits are not simultaneous. 200 ms applies only at 1 Hz. 10 Hz applies only at 20 ms.
- Cooling medium
- Deionized or distilled water
- Water temperature
- 20–30 °C, 25 °C typical
- Pressure
- 0.3–0.4 MPa, 0.35 MPa typical
- Outlet flow
- 3.5–4.5 L/min at the outlet, 4 L/min typical
- Cooling type
- Macro-channel water cooling
- Drawing dimensions
- 40 × 39 × 49 mm per drawing. Axis order follows the drawing. A photographed caliper reading of 49.07 mm is for that sample only and does not replace the drawing.
- Handling notes on the source page
- Start cooling water before applying power. Keep the assembly dry and prevent condensation. Avoid eye and skin exposure to laser radiation. Keep the optical window clean. Operate within the documented ratings. Protect from dust and electrostatic discharge during transport and storage.
